I. Background

Title III of the Energy Policy and Conservation Act of 1975 (42 U.S.C. 6291, et seq.; ``EPCA'') sets forth a variety of provisions designed to improve energy efficiency. (All references to EPCA refer to the statute as amended through the American Energy Manufacturing Technical Corrections Act (AEMTCA), Public Law 112-210 (Dec. 18, 2012)). Part B of title III, which for editorial reasons was redesignated as Part A upon incorporation into the U.S. Code (42 U.S.C. 6291-6309, as codified), establishes the ``Energy Conservation Program for Consumer Products Other Than Automobiles.'' These include residential clothes washers, the subject of today's notice. (42 U.S.C. 6292(a)(7))

Under EPCA, the energy conservation program consists essentially of four parts: (1) Testing, (2) labeling, (3) Federal energy conservation standards,

Page 23063

and (4) certification and enforcement procedures. The testing requirements consist of test procedures that manufacturers of covered products must use as the basis for (1) certifying to DOE that their products comply with the applicable energy conservation standards adopted under EPCA, and (2) making representations about the efficiency of those products. Similarly, DOE must use these test procedures to determine whether the products comply with any relevant standards promulgated under EPCA.

General Test Procedure Rulemaking Process

Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures DOE must follow when prescribing or amending test procedures for covered products. EPCA provides in relevant part that any test procedures prescribed or amended under this section shall be reasonably designed to produce test results that measure energy efficiency, energy use, or estimated annual operating cost of a covered product during a representative average use cycle or period of use and shall not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))

In addition, if DOE determines that a test procedure amendment is warranted, it must publish proposed test procedures and afford the public an opportunity to present oral and written comments on them. (42 U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test procedure, DOE must determine to what extent, if any, the proposed test procedure would alter the measured energy efficiency of any covered product as determined under the existing test procedure. (42 U.S.C. 6293(e))

DOE test procedures for clothes washers are codified at appendices J1 and J2 to 10 CFR part 430 subpart B (hereafter, ``appendix J1'' and ``appendix J2''). DOE most recently amended the test procedures for clothes washers on March 7, 2012 (hereafter, the ``March 2012 final rule''). 77 FR 13888. The March 2012 final rule amended certain provisions in appendix J1 and also established the clothes washer test procedure codified in appendix J2.

Manufacturers of residential clothes washers are required to make representations of energy efficiency using either appendix J1 or appendix J2, as revised by the March 2012 final rule. Manufacturers must use a single test procedure for all representations for a basic model and may not use appendix J1 for certain representations and appendix J2 for other representations. Compliance with DOE's amended standards for residential clothes washers, and the corresponding mandatory use of the test procedure at appendix J2 for all representations, is required as of March 7, 2015. 77 FR 32308 (May 31, 2012) and 77 FR 59719 (October 1, 2012).

II. Summary of the Notice of Proposed Rulemaking

In this NOPR, DOE proposes clarifications and technical amendments to its test procedures for clothes washers at appendix J1 and appendix J2. In addition, DOE proposes amendments to the reporting and verification requirements for residential clothes washers. DOE has determined that today's proposed amendments, as described in section III, would not alter the measured efficiency of clothes washers. The proposed amendments either codify guidance interpreting DOE's existing regulations, provide further clarification of the relevant test procedure provisions, provide improved organization of each section, or correct formatting errors in DOE's clothes washer test procedures.

III. Discussion
Clothes Container Capacity Measurement

1. Capacity Measurement in Appendix J1

Section 3.1 of appendix J1 contains procedures for measuring the clothes container capacity. The capacity measurement procedure involves filling the clothes container with water and determining the volume based on the weight of the added water divided by the water density. Section 3.1.4 specifies that the clothes container be filled manually with water to its ``uppermost edge.''

DOE published guidance on July 6, 2010, clarifying the definition of the uppermost edge of the clothes container for the purpose of performing the capacity measurement. See DOE's guidance document at: http://www1.eere.energy.gov/buildings/appliance_standards/pdfs/clotheswashers_faq1_2010-07-06.pdf.

The guidance document provides detailed descriptions and illustrations of the boundary defining the uppermost edge of the clothes container for both top-loading and front-loading clothes washers. For top-loading vertical-axis clothes washers, DOE's guidance document defines the uppermost edge of the clothes container as the highest point of the innermost diameter of the tub cover. For front-

loading horizontal-axis clothes washers, the guidance document specifies filling the clothes container with water to the highest point of contact between the door and the door gasket. If any portion of the door or the door gasket would occupy the measured volume when the door is closed, that volume must be excluded from the measurement. DOE's guidance document also provides illustrations of the boundary defining the uppermost edge of the clothes container for both top-loading and front-loading clothes washers. The proposed amendments incorporate these clarifications into section 3.1.4 of appendix J1, including the illustrations.

The proposal also further clarifies the appropriate water fill levels for front-loading horizontal-axis clothes washers with concave door shapes and top-loading horizontal-axis clothes washers. For front-

loading horizontal-axis clothes washers with concave door shapes, the capacity measurement would include any space above the plane defined by the highest point of contact between the door and the door gasket, if that area can be occupied by clothing during washer operation. Similarly, for top-loading hojjhrizontal-axis clothes washers, the water fill volume would include any space above the plane of the door hinge, if that area can be occupied by clothing during washer operation. This additional clarification is consistent with the illustrations for these clothes washer types provided in DOE's guidance document.

2. Capacity Measurement in Appendix J2

Section 3.1.4 of appendix J2 specifies the maximum allowable water fill levels for determining the capacity of top-loading and front-

loading clothes washers. For front-loading horizontal-axis clothes washers, section 3.1.4 specifies filling the clothes container to the ``uppermost edge that is in contact with the door seal.'' DOE intended this language to clarify the text in DOE's July 6, 2010 guidance document interpreting appendix J1, but did not intend for the measured capacity values to differ. Since publishing the March 2012 final rule, DOE has become aware of front-loading clothes washer door geometries with complex curvatures that may not have an easily discernible ``uppermost edge'' in contact with the door seal. Therefore, DOE proposes to amend the description of the maximum fill volume for front-

loading clothes washers using the same language as the proposed amendments in appendix J1 and specified in the July 6, 2010 guidance, as described in the previous section. The proposed revision would provide additional clarity by referencing the ``highest point of contact'' rather than the ``uppermost edge,'' and will more

Page 23064

clearly identify the geometric boundary between the door and the door gasket. The proposal would more clearly define the uppermost fill level for a wider range of front-loading clothes washer geometries. As noted above, DOE intends for the measured capacity of a front-loading clothes washer using the proposed revised language to be equivalent to the measured capacity using the current front-loading capacity language in section 3.1.4 of appendix J2.

The proposed amendments to appendix J2 also incorporate illustrations of the boundary defining the uppermost edge of the clothes container for top-loading vertical-axis clothes washers and the boundaries defining the fill volumes for horizontal-axis clothes washers.

3. Capacity Rounding Requirements

In both appendix J1 and appendix J2, the capacity measurement is used to determine the test load sizes as defined in Table 5.1. The table provides test load sizes for capacity ranges in increments of 0.10 cubic feet. The precision of the capacity ranges in Table 5.1 implies that the capacity of the clothes container must be measured to the nearest 0.01 cubic foot for the purpose of determining load size. However, manufacturers typically report capacity to the nearest 0.1 cubic foot in DOE certification reports and in retail advertisements.

The proposed amendments clarify that, under appendix J1 and appendix J2, capacity must be measured to the nearest 0.01 cubic foot not only for the purpose of determining load size, but also for the purpose of calculating the values that manufacturers must report pursuant to 10 CFR 429.20(b). In both appendices, DOE proposes specifying this requirement in a new section 3.1.7 following the calculation of capacity in newly renumbered section 3.1.6.

The proposed amendments would also specify in a new section at 10 CFR 429.20(c) that capacity must be reported to the nearest 0.1 cubic foot (cu. ft.) for the purpose of DOE certification reports for residential clothes washers.

Finally, DOE proposes to clarify in a new section at 10 CFR 429.20(a)(3) that the certified capacity of any clothes washer basic model shall be the mean of the capacities of the units in the sample for the basic model. While DOE believes this is current practice because the existing test procedure and sampling plan require testing at least two units and measuring the drum capacity individually for each, DOE is proposing this amendment for clarity.

4. Plastic Sheet Material

Section 3.1.2 of both appendix J1 and appendix J2 instructs the testing party to line the inside of the clothes container with a 2 mil thickness (0.051mm) plastic sheet in preparation for performing the capacity measurement. DOE is aware that common industry practice is to use a large 2 mil plastic bag, rather than a plastic sheet, for lining the clothes container because the shape of the plastic bag more easily conforms to the geometry of the clothing container. DOE believes the measured capacity of the clothes washer would be the same regardless of whether a plastic sheet or plastic bag is used, provided that the thickness of either the plastic sheet or plastic bag is 2 mil. DOE therefore proposes to amend section 3.1.2 of both appendix J1 and appendix J2 to allow the use of either a 2 mil thickness plastic sheet or plastic bag to line the inside of the clothes container.

5. Shipping Bolts

Typically, front-loading clothes washers are designed with large bolts, inserted through the back of the clothes washer, that secure the wash drum to prevent movement of the drum during shipping. These ``shipping bolts'' must be removed prior to operating the clothes washer. Alternatively, on some front-loading clothes washers, the drum is secured using other forms of bracing hardware that is intended to be removed prior to operating the clothes washer.

Section 3.1.1 of appendix J2 currently specifies that the shipping bolts must remain in place during the capacity measurement procedure to support the wash drum and prevent it from sagging downward as the drum is filled with water. The proposed amendments would add a reference to ``other forms of bracing hardware'' in section 3.1.1 of both appendix J1 and appendix J2.

In addition, DOE has become aware of front-loading clothes washer designs that do not use shipping bolts or other forms of bracing hardware to support the wash drum during shipping. DOE proposes further amending section 3.1.1 of both appendix J1 and J2 to describe how a laboratory should measure the capacity of this type of clothes washer. The proposed amendments would allow a laboratory to support the wash drum by other means, including temporary bracing or support beams. Any temporary bracing or support beams would be required to keep the wash drum in a fixed position, relative to the geometry of the door and door seal components, that is representative of the position of the wash drum during normal operation. The proposal would also require that the method used avoid damage to the unit that would affect the results of the energy and water testing. The proposed amendments further specify that the test report must fully document the method used to support the wash drum, and pursuant to 10 CFR 429.71, the manufacturer must retain such documentation as part of its test records.
Hot and Cold Water Supply Test Conditions

Section 2.3.1 of both appendix J1 and appendix J2 specifies that the temperature of the hot water supply must not exceed 135 degF and the cold water supply must not exceed 60 degF for clothes washers in which electrical energy or water energy consumption are affected by the inlet water temperature (for example, water heating clothes washers or clothes washers with thermostatically controlled water valves). This specification does not provide a lower bound for the hot and cold water supply temperatures. In contrast, section 2.3.2 of both test procedures specifies a hot water supply temperature of 135 degF 5 degF and a cold water supply temperature of 60 degF 5 degF for clothes washers in which electrical energy and water energy consumption are not affected by the inlet water temperature.

On clothes washers with thermostatically controlled mixing valves, the supply water temperatures directly affect the relative quantities of hot and cold water consumption during a wash cycle. DOE has observed that the large majority of residential clothes washers on the market now use thermostatically controlled mixing valves or other similar technologies for precisely controlling the wash water temperatures. DOE's engineering analysis during the most recent energy conservation standards rulemaking indicated that precise temperature control will be required to achieve the higher efficiency levels established by the May 31, 2012 direct final rule. (77 FR 32308)

To improve consistency and repeatability of test results, DOE proposes to establish a lower bound of 130 degF for the hot water supply and 55 degF for the cold water supply for clothes washers in which electrical energy or water energy consumption are affected by the inlet water temperature. This would provide an allowable range of five degrees on the hot and cold water supplies (i.e., 130-135 degF and 55-60 degF, respectively). This amendment would apply to both appendix J1 and appendix J2 (with section 2.3.1 in appendix J2 renumbered to 2.2.1).

Page 23065

DOE notes that the proposed five-degree temperature tolerance is a tighter tolerance than is required for clothes washers in which electrical energy and water energy consumption are not affected by the inlet water temperature; however, DOE notes that the water supply temperature affects the outcome of the MEF results when testing clothes washers with thermostatically controlled water valves more significantly than for clothes washers without such valves. DOE requests comment on the potential test burden associated with maintaining a tolerance of five degrees on the hot and cold water supply temperature for clothes washers in which electrical energy and water energy consumption are affected by the inlet water temperature.
Test Cloth Standard Extractor RMC Test Procedure

Sections 2.6.5 through 2.6.7 of both appendix J1 and appendix J2 contain the procedures for performing the standard extractor remaining moisture content (RMC) test to evaluate the moisture absorption and retention characteristics and to develop a unique correction curve for each new lot of test cloth. To improve the clarity and overall logical flow of the test procedure, DOE proposes moving the contents of sections 2.6.5 through 2.6.7 in both appendices to a new appendix J3 as a standalone test method for measuring the moisture absorption and retention characteristics of new energy test cloth lots.
Test Cloth Loading Instructions

Section 2.8.3 of both appendix J1 and appendix J2 instruct the testing party to load the energy test cloths into the clothes washer by grasping them in the center, shaking them to hang loosely, and then ``put them into the clothes container'' prior to activating the clothes washer. DOE proposes to provide additional specificity for the test cloth handling and loading instructions, which DOE believes will improve the overall clarity and consistency of test cloth loading procedures. The proposed amendments would apply to both appendix J1 and appendix J2 (section 2.8.3 would be renumbered to 2.9.2 in appendix J2 per the proposed amendments).

DOE proposes using a modified version of the loading instructions for towels and pillowcases provided in the Association of Home Appliance Manufacturers (AHAM) HLW-1-2010 test method, Performance Evaluation Procedures for Household Appliances.\1\ Like DOE's current test cloth loading instructions, the AHAM procedure involves grasping the towel/pillowcase in the center and shaking it so that it hangs loosely. The AHAM procedure further describes placing the towels/

pillowcases into the drum with alternating orientations. It also provides sketches illustrating each step in the loading process. DOE's proposed amendments would adopt similar illustrations. The amendments would also specify following any additional manufacturing loading instructions provided to the user regarding the placement of clothing within the clothing container.

Energy Test Cycle

1. Warm Rinse Cycles

Section 1.7 of appendix J1 defines the energy test cycle as (A) the cycle recommended by the manufacturer for washing cotton or linen clothes, including all wash/rinse temperature selections and water levels offered in that cycle, and (B) for each other wash/rinse temperature selection or water level available on that basic model, the portion(s) of other cycle(s) with that temperature selection or water level that, when tested pursuant to these test procedures, will contribute to an accurate representation of the energy consumption of the basic model as used by consumers.

DOE published guidance on September 21, 2010, clarifying that the energy test cycle should include the warm rinse of the cycle most comparable to the cottons and linens cycle if warm rinse is not available on the cottons and linens cycle. See DOE's guidance document at: http://www1.eere.energy.gov/buildings/appliance_standards/pdfs/clotheswasher_faq_2010-09-21.pdf. The proposed amendments codify DOE's guidance by incorporating this clarification into section 1.7(B) of appendix J1 (redesignated as section 1.8(B) due to the proposed addition of a new entry in the list of definitions before the energy test cycle definition).

As described in section III.E.4 of this NOPR, DOE is proposing a new methodology for determining the energy test cycle in appendix J2. Based on the proposed methodology, which is intended to improve clarity without altering the cycle selections that will be part of the energy test cycle, DOE has tentatively determined that a parallel clarification regarding a warm rinse cycle is unnecessary in appendix J2. The methodology for determining the warm wash/warm rinse temperature selection in appendix J2 requires including the warm rinse cycle if it is not available on the cycle recommended for washing cotton or linen clothes but is available on an alternative cycle selection.

2. Sanitization Cycles

As described in the previous section, the energy test cycle in appendix J1 includes all temperature selections available on the cycle recommended by the manufacturer for washing cotton or linen clothing. The energy test cycle also includes other temperature selections available on other cycles that ``will contribute to an accurate representation of the energy consumption of the basic model as used by consumers.''

Section 3.3 of appendix J1 defines the ``Extra Hot Wash'' as a cycle with a maximum wash temperature of greater than 135emsp14degF on water heating clothes washers. DOE is aware that on some clothes washers, an extra hot temperature selection is available only on a separate sanitization cycle. The proposed amendments to the energy test cycle definition in appendix J1 would clarify that for such clothes washers, the sanitization cycle should be included in the energy test cycle if the cycle is recommended by the manufacturer for washing clothing and if doing so would contribute to an accurate representation of the energy consumption as used by consumers. If the extra hot temperature selection is available only on a sanitization cycle not recommended by the manufacturer for washing clothing (e.g., a cycle intended only for sanitizing the wash drum), such a cycle would not be required for consideration as part of the energy test cycle.

Based on DOE's proposed new methodology for determining the energy test cycle in appendix J2, DOE has tentatively determined that a specific clarification regarding a sanitization cycle is unnecessary in appendix J2 because the methodology for determining the extra hot wash temperature selection requires including the extra hot wash temperature setting if such a setting is available on the clothes washer and is recommended by the manufacturer for washing clothing.

3. Default Cycle Settings

Testing a clothes washer according to appendix J1 or appendix J2 requires selecting specific wash/rinse temperatures and wash water fill levels for the wash cycles used to determine energy and water consumption. In addition, specific spin speeds must be

Page 23066

selected for the wash cycle(s) used to determine the remaining moisture content. Other than these settings, the test procedure does not instruct the user to change any other optional settings during testing.

The proposed amendments to appendix J1 would modify section 1.7(B) (redesignated as 1.8(B)) to clarify the requirement to use the manufacturer default settings for any cycle selections, except for (1) the temperature selection, (2) the wash water fill levels, or (3) if necessary, the spin speeds on wash cycles used to determine remaining moisture content. Specifically, the manufacturer default settings must be used for wash conditions such as agitation/tumble operation, soil level, spin speed on wash cycles used to determine energy and water consumption, wash times, rinse times, optional rinse settings, water heating time for water-heating clothes washers, and all other wash parameters or optional features applicable to that wash cycle. Any optional wash cycle feature (other than wash/rinse temperature, water fill level selection, or spin speed on cycle selections used to determine remaining moisture content) that is activated by default on the wash cycle under test must be included for testing unless the manufacturer instructions recommend not selecting this option for washing normally soiled cotton or linen clothes.

The proposed amendments to appendix J2 would add a new section 3.2.7 to address the use of default cycle settings in the same manner as the modification proposed for appendix J1. DOE believes the new section 3.2.7 is the most appropriate location for this amendment in appendix J2 in conjunction with the revised structure of the energy test cycle definition and flowcharts in appendix J2.

4. Energy Test Cycle Definition and Flowcharts

DOE notes that appendix J1 uses the term ``energy test cycle'' in two different ways. In some instances, ``energy test cycle'' refers to the complete set of wash/rinse temperature selections required for testing. In other instances, ``energy test cycle'' refers to the single wash cycle under test. DOE does not propose changing its usage of the term ``energy test cycle'' in appendix J1. In each instance where the term ``energy test cycle'' is used, the specific meaning of the term can be determined through context.

In appendix J2, however, DOE proposes to simplify the definition of the energy test cycle so that it means the complete set of wash/rinse temperature selections required for testing. The individual wash/rinse temperature selections required for testing would be determined using a new methodology as described below. The provisions within parts (D) and (E) of the current energy test cycle definition would be moved to sections 3.2.7 and 3.2.8, respectively, which is a more appropriate location within the test procedure. Additionally, throughout appendix J2, DOE proposes to provide greater consistency in its usage of the term ``energy test cycle,'' such that when used, it refers only to the entire set of wash/rinse temperature selections required for testing. In instances where the test procedure currently uses the term ``energy test cycle'' to refer to an individual wash cycle, DOE proposes to use the generic term ``wash cycle'' or other similar terminology as appropriate for each instance. DOE also proposes to improve overall clarity by providing the full wash/rinse temperature designation (e.g. ``Cold wash/Cold rinse'') throughout the test procedure.

In conjunction with the simplified energy test cycle definition, DOE proposes a new approach to determining the wash/rinse temperature selections required for testing in appendix J2. DOE proposes to translate the current methodology for determining the energy test cycle into a set of flowcharts that testing parties would use to determine each wash/rinse temperature selection to be used for testing. DOE believes that the binary nature of each decision box within the flowcharts would provide increased clarity and ease of use in determining which wash/rinse temperature settings to use for testing. DOE proposes to include these flowcharts within newly renumbered section 2.12 in appendix J2.

Because the proposed flowcharts would incorporate more precise definitions of warm and cold rinse temperatures, DOE also proposes to clarify the definition of ``cold rinse'' in appendix J2 so that it means the coldest rinse temperature available on the machine, as indicated to the user on the clothes washer control panel. This would prevent the unintended consequence of a wash/rinse temperature designation being excluded from the energy test cycle if the rinse portion of the cycle included a small amount of hot water (thus raising the rinse temperature slightly higher than the coldest rinse available on the machine), but was indicated on the control panel as being a cold rinse paired with the selected wash temperature.

In addition, DOE proposes adding a new definition in appendix J2 for ``Normal cycle,'' which would be defined as: ``Normal cycle means the cycle selection recommended by the manufacturer as the most common consumer cycle for washing a full load of normally to heavily soiled cotton clothing. For machines where multiple cycle settings meet this description, then the Normal cycle is the cycle selection that results in the lowest IMEF or MEF value.'' ''. DOE first adopted a similar definition of ``Normal cycle'' for clothes washer testing in appendix J, which incorporated the general approach to calculating the energy consumption of automatic clothes washers contained in AHAM's standard HLW-2EC for clothes washers at the time. (42 FR 25329, 25330 (May 17, 1977); 42 FR 49802 (September 28, 1977)) Over time, machine labeling and literature evolved to the point that the term ``normal'' as previously defined no longer captured all of the control settings most consumers would typically choose in operating the machine to wash their laundry. (See, e.g., 75 FR 57556, 57575) Further, the range of cycle options and terminology on the control panels have changed such that many machines no longer refer to a ``Normal'' cycle, instead relying upon other terms. This evolution may have resulted in inaccurate representations of the energy usage of these machines due to differing interpretations regarding the appropriate test cycle. In order to add clarity and ensure consistent selection of the appropriate cycle for energy testing, DOE is proposing to add the ``Normal cycle'' definition in newly designated section 1.25 and to reference the term in the new energy test cycle flowcharts, and DOE will consider manufacturer literature and markings on the machine when determining the normal cycle of any particular unit. DOE specifically seeks comment on this definition and whether it adequately covers the cycle setting most commonly chosen by users of washing machines.

DOE also proposes to remove the definitions for ``warm rinse'' and ``warm wash'' from section 1 of appendix J2 (Definitions and Symbols), since those terms would be defined in the proposed flowcharts instead.

Finally, DOE proposes to move the current section 2.13 of appendix J2, Energy consumption for the purpose of certifying the cycle selection(s) to be included in Part (B) of the energy test cycle definition, to newly created section 3.10. Section 3 of appendix J2 (Test Measurements), is a more appropriate location in the test procedure for these provisions.

Page 23067

DOE intends for the cycle selections as determined using the new energy test cycle flowcharts to be the same as the cycle selections as determined using the current energy test cycle definition in appendix J2. DOE requests comment on whether discrepancies exist when determining the wash/rinse temperature selections using the proposed flowcharts compared to using the current energy test cycle definition. If discrepancies exist, DOE requests that interested parties provide specific examples of cycle setting configurations that would lead to the discrepancies. DOE also requests comment on whether the methodology presented in the flowcharts could result in an efficiency rating that is unrepresentative of how a particular clothes washer would be used by consumers.
Wash Time Setting

DOE proposes moving the wash time setting provisions from section 2.10 of appendix J2 to a subsection of newly revised section 3.2.5. The procedure for setting the wash time must be performed prior to each individual wash cycle during testing; therefore, the most appropriate location for this instruction is within the specific testing procedures provided in section 3.2.
Standby and Off Mode Testing

DOE proposes clarifications to the standby and off mode power testing provisions in appendix J2. In addition to minor wording clarifications in sections 3.9 and 3.9.1 of appendix J2, the proposed clarifications are as follows:

1. Testing Sequence

DOE proposes clarifying that combined low-power mode testing in section 3.9 of appendix J2 be performed after completion of an energy test cycle, after removing the test load, and without disconnecting the electrical energy supply to the clothes washer between completion of the energy test cycle and the start of combined low-power mode testing. This clarification would preclude performing combined low-power mode testing directly after connecting the clothes washer to the electrical energy supply. DOE testing suggests that testing a clothes washer's standby or off-mode power consumption directly after connecting the clothes washer to the electrical energy supply may not be representative of the standby or off-mode power consumption after its first use. DOE believes this clarification would ensure that the results of the combined low-power mode testing accurately represent the conditions most likely to be experienced in a residential setting.

2. Default Settings

DOE proposes clarifying that combined low-power mode testing be performed without changing the control panel settings used for the energy test cycle completed prior to combined low-power mode testing. The test procedure requires using the manufacturer default settings for any wash cycle performed within the energy test cycle. The proposed clarification would preclude activating or deactivating any optional control panel displays or other features not activated by default on the clothes washer when it is not being used to perform an active mode wash cycle, during combined low-power mode testing. DOE believes this clarification would ensure that the results of the combined low-power mode testing accurately represent the conditions most likely to be experienced in a residential setting.

3. Multiple Possible Inactive Modes

DOE testing indicates that some residential appliances, including clothes washers, may have multiple modes that meet the definition of inactive mode currently provided in section 1.15 of appendix J2 (redesignated section 1.16). DOE proposes clarifying that inactive mode is the lowest-power standby mode that facilitates the activation of active mode by remote switch (including remote control), internal sensor, or timer, or that provides continuous status display. Specifying use of the lowest-power mode would clarify potential ambiguity regarding which inactive mode to use for testing if multiple inactive modes exist on a clothes washer.
Fixed Water Fill Control Systems

The load sizes used for testing depend upon the type of water fill control system available on the clothes washer, as defined in section 2.8 of both appendix J1 and appendix J2. For clothes washers with manual water fill control systems, the minimum and maximum load sizes are tested. For clothes washers with adaptive water fill control systems, the minimum, average, and maximum load sizes are tested.

DOE has become aware of clothes washers that have fixed water levels for all load sizes and no water fill selector or water fill control settings available to the user. DOE notes that, as with adaptive water fill control systems, fixed water fill control systems do not require user action to determine the water fill level. Therefore, DOE proposes that a clothes washer with a fixed water fill control system be tested in the same manner as a clothes washer with an adaptive water fill control system; i.e., using the minimum, average, and maximum load sizes.

The proposed amendments would (1) add a definition for ``fixed water fill control system,'' (2) add a definition for ``automatic water fill control system,'' which would include both fixed water fill control systems and adaptive water fill control systems, and (3) amend the definition of ``adaptive water fill control system'' to clarify that it is considered a type of automatic water fill control system. Additionally, where appropriate, instances of ``adaptive water fill control system'' throughout the test procedure would be replaced with ``automatic water fill control system,'' to indicate that such testing provisions apply to both adaptive water fill control systems and fixed water fill control systems. These amendments would apply to both appendix J1 and appendix J2.

I. Deep Rinse and Spray Rinse Definitions

Section 3.2.2 of appendix J2 states that total water consumption during the energy test cycle shall be measured, including hot and cold water consumption, during wash, deep rinse, and spray rinse. As proposed, the revised section 3.2.8 would specify including the entire active washing mode, and excluding any delay start or cycle finished modes, for each wash cycle tested. Active washing mode is defined in section 1.2 as including the main functions of washing, soaking, tumbling, agitating, rinsing, and/or removing water from the clothing. DOE believes that the proposed revision to 3.2.8 provides better clarity and completeness, compared to the wording in 3.2.2, regarding the portions of the wash cycle to be included and measured for testing. Therefore, DOE proposes to delete section 3.2.2 from appendix J2 and to renumber the subsequent subsections accordingly.

Furthermore, since section 3.2.2 is the only location within the test procedure where the terms ``deep rinse'' and ``spray rinse'' occur, DOE also proposes to remove those two definitions from the section 1 of appendix J2.
Uniformly Distributed Warm Wash Temperatures

Section 1.17 of appendix J1 and section 1.32 of appendix J2 provide the definition of uniformly distributed warm wash temperature selections. A clothes washer has uniformly distributed warm wash temperature selections if (A) the warm wash temperatures have a linear relationship with all discrete warm wash selections

Page 23068

when the water temperatures are plotted against equally spaced consecutive warm wash selections between the hottest warm wash and the coldest warm wash, and the mean water temperature of the warmest and the coldest warm selections coincide with the mean of the hot wash and cold wash water temperatures within 3.8emsp14degF; or (B) on a clothes washer with only one warm wash temperature selection, the warm wash temperature selection has a water temperature that coincides with the mean of the hot wash and cold wash water temperatures within 3.8emsp14degF. For clothes washers with uniformly distributed warm wash temperature selections, the reported values to be used for the warm wash setting are the arithmetic average of the measurements for the hot and cold wash selections. This is a ``shortcut'' calculation only; no testing is required.

DOE notes that the criteria for determining whether the warm wash temperatures are uniformly distributed are based on water temperature only; total water consumption is not considered. On a clothes washer with electronic control systems, a clothes washer's warm wash cycles could be programmed to use larger quantities of water than the cold wash and hot wash cycles, yet the data to be used to represent the warm wash cycle would be the average of the cold and hot wash cycles, rather than actual data from testing. Since the warm wash temperature selection has the highest temperature use factor at 0.49, DOE proposes that the warm wash temperature selection(s) on such a clothes washer be tested. Therefore, DOE proposes to remove the definition of uniformly distributed warm wash temperature selections from both appendix J1 and appendix J2, and to remove any provisions within the test procedures pertaining to uniformly distributed warm wash temperature selections.

DOE requests comment on any potential increase in test burden as result of its proposal to eliminate the separate testing provisions for clothes washers with uniformly distributed warm wash temperatures. DOE estimates that the resulting total testing time would be no greater than for clothes washers with the same number of warm wash temperature options, but with non-uniformly distributed temperatures, which DOE observes constitutes the majority of the market.
Determining Extra Hot Wash Temperature

Section 3.3 of both appendix J1 and appendix J2 defines Extra Hot Wash as having a maximum wash temperature greater than 135emsp14degF. Determining the maximum wash temperature requires measuring the water temperature during the wash cycle to determine the maximum wash temperature achieved. DOE understands that, in practice, measuring the wash water temperature can be difficult due to factors such as the geometry of front-loading tub design; the increasing use of door locks; and, in high-efficiency clothes washers, the lack of a standing pool of wash water from which to measure the temperature.

DOE proposes adding a statement to section 3.3 of both appendix J1 and appendix J2 to provide guidance on one possible method that testing parties could use to determine the maximum wash water temperature. In the proposed method, testing parties would adhere non-reversible temperature indicator labels to the inside of the clothing container to determine the maximum water temperature during an energy test cycle. If a testing party used the temperature indicator label method when testing a front-loading clothes washer, the label would be adhered along the inner circumference of the clothes container drum, midway between the front and the back of the clothes container. For a top-

loading clothes washer, the label would be adhered along the inner circumference of the clothes container drum, as close to the bottom of the container as possible.

Manufacturers may be able to use alternate methods for determining the maximum wash temperature during an energy test cycle; however, DOE is unaware of any other direct measurement methods that could be safely used by a third-party laboratory without requiring partial disassembly of the clothes washer or without permanently altering the machine.

L. Gas-Heated and Oil-Heated Hot Water Energy

Section 4.1.4 of both appendix J1 and appendix J2 provides equations for calculating per-cycle hot water energy consumption using gas-heated or oil-heated water. The result of this calculation is not used in any downstream calculations within the test procedure. The calculated result is referenced within 10 CFR 430.23(j)(1)(i)(B) and (ii)(B); however, these values are not included as part of DOE's certification requirements for clothes washers in 10 CFR 429.20 and 429.46, nor are they required for other DOE regulatory purposes. DOE is unaware of any other regulatory programs that require the calculation of per-cycle hot water energy using gas- or oil-heated water for clothes washers. Therefore, DOE proposes to remove section 4.1.4 from both appendix J1 and appendix J2, and to remove the related sections of 10 CFR 430.23(j)(1)(i)(B) and (ii)(B), adjusting the subsequent section numberings accordingly.
Out-of-Balance Loads

DOE has observed that some clothes washers may terminate the wash cycle prematurely if an out-of-balance condition is detected. Because the test procedure defines an energy test cycle as including the agitation/tumble operation, spin speed(s), wash times, and rinse times applicable to each cycle, the data from a wash cycle that terminates prematurely if an out-of-balance condition is detected, and thus does not include these required elements, should be discarded. The proposed amendments provide this clarification to section 3.2 of appendix J1 and a new section 3.2.9 of appendix J2.
Reordering of Section 2, Testing Conditions

DOE proposes to reorder the subsections within section 2 of appendix J2 (Testing Conditions) to improve the clarity and overall flow of the section. After reordering, the general progression of section 2 would be as follows:

Laboratory infrastructure requirements

Instrumentation requirements

Test cloth requirements

Test load composition and handling

Clothes washer installation and preconditioning procedures

Energy test cycle determination
Table 3.2 Edits

Table 3.2 in both appendix J1 and appendix J2 defines the sections within the test procedure that govern the tests of particular clothes washers, based on the number of wash/rinse temperature selections available on the model. DOE proposes to clarify one of the headings in Table 3.2 of appendix J1. The proposal would amend the current heading, ``Number of wash temp. selections'' to ``Number of wash temp. selections in the energy test cycle.'' In addition, Table 3.2 in appendix J1 contains a typographical error in the second footnote: the word ``heating'' is misspelled. Today's proposal corrects this error.

DOE proposes simplifying the overall structure of Table 3.2 in appendix J2 (renumbered 3.2.2) by using the clarified wash/rinse temperature nomenclature within the revised energy

Page 23069

test cycle definition and flowcharts. DOE does not intend for any of the required test sections to change as a result of the proposed revisions to the table.
Table 4.1.1 Edits

Table 4.1.1 in appendix J2 provides the temperature use factors. DOE proposes improving the clarity of the overall structure of Table 4.1.1 in appendix J2 by reorganizing the columns in the table to more closely match the wash/rinse temperature nomenclature within the revised energy test cycle definition and flowcharts. DOE does not intend for any of the temperature use factors to change as a result of the proposed revisions to the table.
Table 2.8 Edits

In the March 2012 final rule, Table 2.8 in appendix J2 (``Test Load Sizes and Water Fill Settings Required'') contained a formatting error that combined the average and minimum test load sizes into a single row for clothes washers with an adaptive water fill control system. DOE did not intend to amend the test load sizes required for clothes washers with an adaptive water fill control system. Today's proposal amends the layout of Table 2.8 in both appendix J1 and appendix J2 to improve its overall clarity. As described above, DOE has also proposed changing the heading of the relevant column to ``automatic water fill control system'' rather than ``adaptive water fill control system''.
Replacing ``Consumer'' With ``User''

Both appendix J1 and appendix J2 refer to the ``consumer'' in various parts of the test procedures. In each instance, the word ``consumer'' refers to the individual using the clothes washer. DOE notes that the word ``consumer'' may be misconstrued as the original purchaser or owner of the clothes washer. In some cases, particularly coin-operated laundries and multi-family housing common laundry rooms, the purchaser or owner of the clothes washer is not the end user of the clothes washer.

The distinction between the owner and the end user may be relevant to the test procedure if certain settings, such as water fill levels, may be customized by the owner of the clothes washer but are not adjustable by the end user. To prevent any possible ambiguity implied by the word ``consumer,'' DOE proposes to replace the word ``consumer'' with ``user'' or ``end user'' throughout the test procedure in all instances where the word ``consumer'' is currently used.
Introductory Text

DOE proposes revising the introductory text after the appendix headings in both appendix J1 and appendix J2 to clarify the proper use of appendices J1 and J2 for making representations of energy efficiency, including certifying compliance with DOE energy conservation standards.

DOE test procedures for clothes washers are set forth in appendices J1 and J2 in 10 CFR Part 430 subpart B. This proposal describes amendments to both appendices. Pursuant to 42 U.S.C. 6293(c), manufacturers must make representations of energy efficiency using any amendments DOE adopts in a final test procedure rule beginning 180 days after the effective date of such rule. Therefore, beginning 180 days after the effective date of any final amendments based on today's proposals, manufacturers must make representations of energy efficiency pursuant to appendix J1 or appendix J2 as modified through such amendments.

In addition, as of March 7, 2015, manufacturers of residential clothes washers will no longer be authorized to use appendix J1. Residential clothes washer manufacturers must use appendix J2, as modified though any amendments that DOE may adopt based on today's proposal, to demonstrate compliance with the standards and make any representations of energy efficiency as of March 7, 2015. March 7, 2015 is the compliance date of the amended energy conservation standards that address standby and off mode energy consumption for residential clothes washers. 77 FR 32308 (May 31, 2012) and 77 FR 59719 (October 1, 2012).
Test Procedure Provisions in 10 CFR 430.23

DOE proposes revising section 430.23(j)(3) to contain only the provisions for calculating annual water consumption when using either appendix J1 or appendix J2. The proposed amendments would add a new section 430.23(j)(4), which would contain the provisions for determining water factor and integrated water factor.

The proposed amendments would also create a new section 430.23(j)(5) that would contain the following statement: ``Other useful measures of energy consumption for automatic or semi-automatic clothes washers shall be those measures of energy consumption that the Secretary determines are likely to assist consumers in making purchasing decisions and that are derived from the application of appendix J1 or appendix J2, as appropriate.'' This statement is currently contained in section 430.23(j)(3). Moving the statement to a dedicated subsection would maintain consistency with DOE's test procedure provisions for other products within 10 CFR Part 430. DOE notes that the measurement or reporting of any additional measures of energy or water consumption would be adopted through the rulemaking process.

Finally, to eliminate any potential ambiguity, the proposed amendments would replace the phrase ``can be determined'' with ``must be determined'' throughout the text of 10 CFR 430.23(j)(3) through (j)(5).
Reporting and Verification Requirements

1. Remaining Moisture Content

DOE has observed the potential for significant variation in the RMC measurement at the maximum spin speed setting on some clothes washer models. During testing of front-loading clothes washer models, DOE observed that the maximum target spin speed may not be achieved during the final spin portion of the cycle if the load size is not evenly distributed around the circumference of the wash drum. DOE believes that in such cases, the spin speed may be automatically reduced as a safety precaution and to prevent damage to the clothes washer caused by the asymmetric rotation of the unbalanced load within the wash basket.

Figure III.1 shows an example of RMC test data obtained from one front-loading residential clothes washer model. DOE performed the RMC measurement using the cold wash cycle at the maximum available spin speed setting. The RMC measurement was performed a total of twelve times using three different test cloth lots. The corrected RMC measurement \2\ varied between 32.3 percent and 46.2 percent, with an average of 37.0 percent. DOE has observed similar variations of this magnitude on multiple front-loading clothes washer models.

---------------------------------------------------------------------------

\2\ Corrected RMC measurements are obtained using the test cloth correction factors developed for each test cloth lot, as applied in section 2.6.7 of appendix J1 and appendix J2. DOE publishes a list of the test cloth correction factors developed for test cloth Lots 5 through 20 at http://www2.eere.energy.gov/buildings/appliance_standards/residential/clothes_washer_test_cloth_correction.html.

---------------------------------------------------------------------------

Page 23070

GRAPHIC TIFF OMITTED TP25AP14.014

The RMC measurement is used to determine the per-cycle energy consumption for removal of moisture from the test load; i.e., the ``drying energy'' portion of the MEF and Integrated Modified Energy Factor (IMEF) calculations. The drying energy represents between 59 and 87 percent of a clothes washer's total energy consumption; \3\ hence, the RMC measurement significantly impacts the overall MEF and IMEF calculations. For example, the level of RMC variation shown in Figure III.1 would lead to a 25 percent variation in the overall MEF calculation.

---------------------------------------------------------------------------

\3\ Percentages derived from Table 7.2.1 and 7.2.2 in the May 31, 2012 direct final rule technical support document for the residential clothes washer energy conservations standards rulemaking, available at http://www.regulations.gov/#!documentDetail;D=EERE-2008-BT-STD-0019-0047.

---------------------------------------------------------------------------

In today's rule, DOE proposes adding a new section 3.8.5 in both appendix J1 and appendix J2 to specify that manufacturers may perform up to two additional replications of the RMC measurement, for a total of three independent RMC measurements for the tested unit, and use the average of the three measurements as the basis for the calculation of per-cycle energy consumption for removal of moisture from the test load.

DOE also proposes to add the RMC measurement to the list of public product-specific information contained in the certification reports for residential clothes washers, as described in 10 CFR 429.20(b)(2)(i) and (ii). DOE also proposes in newly created 10 CFR 429.20(a)(4) that the certified RMC value of any clothes washer basic model shall be the mean of the final RMC value measured for all tested units of the basic model.

Finally, DOE proposes to add provisions in newly created section 10 CFR 429.134(c)(1) specifying that during assessment or enforcement testing, the measured RMC value of a tested unit will be considered the tested unit's final RMC value if the measured RMC value is within two RMC percentage points of the certified RMC value of the basic model (expressed as a percentage), or if the measured RMC value is lower than the certified RMC value. DOE proposes a threshold of two RMC percentage points because such a variation would limit the variation in the overall MEF or IMEF calculation to roughly five percent.

If the measured RMC value of a tested unit is more than two RMC percentage points higher than the certified RMC value of the basic model, DOE will perform two additional replications of the RMC measurement, each pursuant to the provisions of newly added section 3.8.5 of appendix J1 and appendix J2, for a total of three independent RMC measurements of the tested unit. The average of the three RMC measurements will be considered the tested unit's final RMC value and will be used as the basis for the calculation of per-cycle energy consumption for removal of moisture from the test load for that unit.

2. Rounding Requirements for All Reported Values

DOE proposes adding a new section at 10 CFR 429.20(c) to specify the rounding requirements of all reported values for residential clothes washers as follows: MEF and IMEF to the nearest 0.01 cu ft/kWh/

cycle, WF and IWF to the nearest 0.1 gal/cycle/cu ft, RMC to the nearest 0.1 percentage point, and clothes container capacity to the nearest 0.1 cu ft.

3. Energy Test Cycle Selections

As amended by the March 2012 final rule, 10 CFR 429.20(b)(3) requires certification reports based on testing conducted in accordance with appendix J2 to include a list of all cycle selections comprising the complete energy test cycle for each basic model. DOE believes that this reporting requirement should also pertain when appendix J1 is used, particularly due to the difference in wording of the energy test cycle definition in appendix J1. Therefore, DOE proposes to amend 10 CFR 429.20(b)(3) to require a list of all cycle selections comprising the complete energy test cycle for each basic model, regardless of whether the certification is based on testing conducted in accordance with appendix J1 or appendix J2.

IV. Procedural Issues and Regulatory Review
Review Under Executive Order 12866

The Office of Management and Budget has determined that test procedure

Page 23071

rulemakings do not constitute ``significant regulatory actions'' under section 3(f) of Executive Order 12866, Regulatory Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this action was not subject to review under the Executive Order by the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget (OMB).
Review Under the Regulatory Flexibility Act

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires preparation of a regulatory flexibility analysis (IFRA) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by Executive Order 13272, ``Proper Consideration of Small Entities in Agency Rulemaking,'' 67 FR 53461 (August 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the potential impacts of its rules on small entities are properly considered during the DOE rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the Office of the General Counsel's Web site: http://energy.gov/gc/office-general-counsel.

DOE reviewed today's proposed rule under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. Today's NOPR would amend DOE's test procedure by codifying guidance interpreting DOE's existing regulations, providing further clarifying interpretation of the relevant test procedure provisions, correcting formatting errors, providing improved overall organization, and removing certain testing provisions within the current test procedures. DOE has concluded that the rule would not have a significant impact on a substantial number of small entities. The factual basis for this certification is as follows:

The Small Business Administration (SBA) considers a business entity to be a small business, if, together with its affiliates, it employs less than a threshold number of workers specified in 13 CFR Part 121. These size standards and codes are established by the 2007 North American Industry Classification System (NAICS). The threshold number for NAICS classification code 335224, which applies to household laundry equipment manufacturers and includes residential clothes washer manufacturers, is 1,000 employees. Searches of the SBA Web site \4\ to identify clothes washer manufacturers within this NAICS code identified one small business. This small business manufactures laundry appliances, including residential clothes washers.

---------------------------------------------------------------------------

\4\ A searchable database of certified small businesses is available online at: http://dsbs.sba.gov/dsbs/search/dsp_dsbs.cfm.

---------------------------------------------------------------------------

DOE estimates that the clarified description of the capacity measurement would take the same amount of time to conduct as the capacity measurement analyzed in the March 2012 final rule. DOE believes that use of an alternate bracing method for front-loading clothes washers that do not contain shipping bolts or other bracing hardware is already current practice among manufacturers of such clothes washers. Additionally, DOE notes that the identified small business produces only a single platform of top-loading clothes washers, for which the proposed alternate bracing method would not be applicable.

Regarding the potential increased testing burden associated with maintaining a five degree tolerance on supply water temperatures for clothes washers in which electrical energy consumption or water energy consumption are affected by the inlet water temperature. One method for achieving this temperature tolerance would be to use electronically controlled water mixing valves on both the cold and hot water supply lines. DOE estimates a capital cost of approximately $2,500 for installing electronically controlled water mixing valves on a single test stand. DOE notes that the identified small business currently does not manufacturer this type of clothes washer; therefore, DOE does not expect this proposed amendment to require any changes to the testing hardware currently used by the small business.

DOE does not expect any of the clarifications to the energy test cycle definition or the standby and off mode measurements to affect the total length of testing time. Regarding any potential increase in test burden as a result of its proposal to eliminate the separate testing provisions for clothes washers with uniformly distributed warm wash temperatures. DOE notes that the total testing time would be no greater than for clothes washers with the same number of warm wash temperature options, but with non-uniformly distributed temperatures, which DOE observes constitutes the majority of the market. DOE also notes that the clothes washers manufactured by the identified small business do not contain uniformly distributed warm wash temperatures, and thus the small business will not be affected by the proposed amendment.

Finally, the remaining proposed changes in today's NOPR are intended to clarify the existing test methods without adding any additional requirements and therefore would not result in additional burden.

For the reasons stated above, DOE certifies that the proposed test procedure amendments would not have a significant impact on a substantial number of small entities. DOE will submit a certification and supporting statement of factual basis to the Chief Counsel for Advocacy of the SBA for review under 5 U.S.C. 605(b).
Review Under the Paperwork Reduction Act of 1995

Manufacturers of residential clothes washers must certify to DOE that their products comply with any applicable energy conservation standards. In certifying compliance, manufacturers must test their products according to the DOE test procedures for clothes washers, including any amendments adopted for those test procedures. DOE has established regulations for the certification and recordkeeping requirements for all covered consumer products and commercial equipment, including residential clothes washers. (76 FR 12422 (March 7, 2011). The collection-of-information requirement for the certification and recordkeeping is subject to review and approval by OMB under the Paperwork Reduction Act (PRA). This requirement has been approved by OMB under OMB control number 1910-1400. Public reporting burden for the certification is estimated to average 20 hours per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

Notwithstanding any other provision of the law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the PRA, unless that collection of information displays a currently valid OMB Control Number.
Review Under the National Environmental Policy Act of 1969

In this proposed rule, DOE proposes test procedure amendments that it expects will be used to develop and implement future energy conservation standards for residential clothes washers. DOE has determined that this rule falls into a class of actions that are categorically excluded from review

Page 23072

under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE's implementing regulations at 10 CFR Part 1021. Specifically, this proposed rule would amend the existing test procedures without affecting the amount, quality or distribution of energy usage, and, therefore, would not result in any environmental impacts. Thus, this rulemaking is covered by Categorical Exclusion A5 under 10 CFR Part 1021, subpart D, which applies to any rulemaking that interprets or amends an existing rule without changing the environmental effect of that rule. Accordingly, neither an environmental assessment nor an environmental impact statement is required.
Review Under Executive Order 13132

Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 1999) imposes certain requirements on agencies formulating and implementing policies or regulations that preempt State law or that have Federalism implications. The Executive Order requires agencies to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and to carefully assess the necessity for such actions. The Executive Order also requires agencies to have an accountable process to ensure meaningful and timely input by State and local officials in the development of regulatory policies that have Federalism implications. On March 14, 2000, DOE published a statement of policy describing the intergovernmental consultation process it will follow in the development of such regulations. 65 FR 13735. DOE examined this proposed rule and determined that it will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. EPCA governs and prescribes Federal preemption of State regulations as to energy conservation for the products that are the subject of today's proposed rule. States can petition DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further action is required by Executive Order 13132.
Review Under Executive Order 12988

Regarding the review of existing regulations and the promulgation of new regulations, section 3(a) of Executive Order 12988, ``Civil Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal agencies the general duty to adhere to the following requirements: (1) Eliminate drafting errors and ambiguity; (2) write regulations to minimize litigation; (3) provide a clear legal standard for affected conduct rather than a general standard; and (4) promote simplification and burden reduction. Section 3(b) of Executive Order 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation: (1) Clearly specifies the preemptive effect, if any; (2) clearly specifies any effect on existing Federal law or regulation; (3) provides a clear legal standard for affected conduct while promoting simplification and burden reduction; (4) specifies the retroactive effect, if any; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under any guidelines issued by the Attorney General. Section 3(c) of Executive Order 12988 requires Executive agencies to review regulations in light of applicable standards in sections 3(a) and 3(b) to determine whether they are met or it is unreasonable to meet one or more of them. DOE has completed the required review and determined that, to the extent permitted by law, this proposed rule meets the relevant standards of Executive Order 12988.
Review Under the Unfunded Mandates Reform Act of 1995

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments and the private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). For a proposed regulatory action likely to result in a rule that may cause the expenditure by State, local, and Tribal governments, in the aggregate, or by the private sector of $100 million or more in any one year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish a written statement that estimates the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to develop an effective process to permit timely input by elected officers of State, local, and Tribal governments on a proposed ``significant intergovernmental mandate,'' and requires an agency plan for giving notice and opportunity for timely input to potentially affected small governments before establishing any requirements that might significantly or uniquely affect small governments. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA. 62 FR 12820; also available at http://energy.gov/gc/office-general-counsel. DOE examined today's proposed rule according to UMRA and its statement of policy and determined that the proposal contains neither an intergovernmental mandate, nor a mandate that may result in the expenditure of $100 million or more in any year, so these requirements do not apply.
Review Under the Treasury and General Government Appropriations Act, 1999

Section 654 of the Treasury and General Government Appropriations Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well-being. This rule would not have any impact on the autonomy or integrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking Assessment.

I. Review Under Executive Order 12630

DOE has determined, under Executive Order 12630, ``Governmental Actions and Interference with Constitutionally Protected Property Rights'' 53 FR 8859 (March 18, 1988), that this regulation would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution.
Review Under Treasury and General Government Appropriations Act, 2001

Section 515 of the Treasury and General Government Appropriations Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most disseminations of information to the public under guidelines established by each agency pursuant to general guidelines issued by OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has reviewed today's proposed rule under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines.
Review Under Executive Order 13211

Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to OMB, a Statement of Energy Effects for any proposed significant energy action. A ``significant energy action'' is defined as

Page 23073

any action by an agency that promulgated or is expected to lead to promulgation of a final rule, and that: (1) Is a significant regulatory action under Executive Order 12866, or any successor order; and (2) is likely to have a significant adverse effect on the supply, distribution, or use of energy; or (3) is designated by the Administrator of OIRA as a significant energy action. For any proposed significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use should the proposal be implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use.

Today's regulatory action to amend the test procedure for measuring the energy efficiency of residential clothes washers is not a significant regulatory action under Executive Order 12866. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy, nor has it been designated as a significant energy action by the Administrator of OIRA. Therefore, it is not a significant energy action, and, accordingly, DOE has not prepared a Statement of Energy Effects.

L. Review Under Section 32 of the Federal Energy Administration Act of 1974

Under section 301 of the Department of Energy Organization Act (Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the Federal Energy Administration Act of 1974, as amended by the Federal Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA) Section 32 essentially provides in relevant part that, where a proposed rule authorizes or requires use of commercial standards, the notice of proposed rulemaking must inform the public of the use and background of such standards. In addition, section 32(c) requires DOE to consult with the Attorney General and the Chairman of the Federal Trade Commission (FTC) concerning the impact of the commercial or industry standards on competition. DOE is not requiring the use of any new commercial standards in this rulemaking, so these requirements do not apply.

It is DOE's policy that all comments may be included in the public docket, without change and as received, including any personal information provided in the comments (except information deemed to be exempt from public disclosure).
Issues on Which DOE Seeks Comment

Although DOE welcomes comments on any aspect of this proposal, DOE is particularly interested in receiving comments and views of interested parties concerning the following issues:

(1) The normal cycle definition and whether it adequately covers the cycle setting most commonly chosen by users of washing machines;

(2) The potential test burden associated with maintaining a tolerance of five degrees on the hot and cold water supply temperature ranges for clothes washers in which electrical energy and water energy consumption are affected by the inlet water temperature;

(3) The potential increase in test burden associated with removing the separate testing provisions for clothes washers with uniformly distributed warm wash temperatures.

(4) Whether any discrepancies exist when determining the wash/rinse temperature selections comprising the energy test cycle in appendix J2 using the proposed flowcharts compared to using the current energy test cycle definition (and, if so, specific examples of cycle setting configurations that would lead to the discrepancies); and

(5) Whether the methodology presented in the energy test cycle flowcharts in appendix J2 could result in an efficiency rating unrepresentative of how a particular clothes washer would be used by consumers.

  (A) All wash/rinse temperature selections and water levels offered in the cycle recommended by the manufacturer for washing cotton or linen clothes, and
  
  (B) For each other wash/rinse temperature selection or water level available on that basic model, the portion(s) of other cycle(s) with that temperature selection or water level that, when tested pursuant to these test procedures, will contribute to an accurate representation of the energy consumption of the basic model as used by end users.
  
  If a warm rinse temperature selection is available on the clothes washer but is not available in the cycle recommended for washing cottons or linens, the energy test cycle shall include the warm rinse temperature selection in the cycle most comparable to the cycle recommended for washing cottons or linens.
  
  If an extra hot temperature selection is only available on a sanitization cycle, the sanitization cycle should be included in the energy test cycle if the cycle is recommended by the manufacturer for washing clothing, and if doing so would contribute to an accurate representation of the energy consumption as used by consumers.
  
  For any cycle under (A) or (B) of this section, use the manufacturer default settings, except for (1) the temperature selection, (2) the wash water fill levels, or (3) if necessary, the spin speeds on wash cycles used to determine remaining moisture content. This includes wash conditions such as agitation/tumble operation, soil level, spin
  
  Page 23076
  
  speed on wash cycles used to determine energy and water consumption, wash times, rinse times, optional rinse settings, water heating time for water-heating clothes washers, and all other wash parameters or optional features applicable to that wash cycle. Include any optional wash cycle feature for testing (other than wash/rinse temperature, water fill level selection, or spin speed on wash cycles used to determine remaining moisture content) that is activated by default on the wash cycle under test unless the manufacturer instructions recommend not selecting this option for washing normally soiled cotton or linen clothes.
  
  1.9 Fixed water fill control system means a clothes washer automatic water fill control system that does not adjust the water fill level based on the size or weight of the clothes load placed in the clothes container.

  To load the energy test cloths in a top-loading clothes washer, arrange the cloths circumferentially around the axis of rotation of the clothes container, using alternating lengthwise orientations for adjacent pieces of cloth. Complete each cloth layer across its horizontal plane within the clothes container before adding a new layer. Figure 2.8.3.2 of this appendix illustrates the correct loading technique for a vertical-axis clothes washer.
  
  To load the energy test cloths in a front-loading clothes washer, arrange the cloths lengthwise, from front to back, using alternating orientations for adjacent pieces of cloth. Load the cloths evenly across the width of the clothes container. Complete each cloth layer across its horizontal plane within the clothes container before adding a
  
  Page 23077
  
  new layer. Figure 2.8.3.3 of this appendix illustrates the correct loading technique for a horizontal-axis clothes washer.
  
  For all clothes washers, follow any additional manufacturer loading instructions provided to the user regarding the placement of clothing within the clothing container.

  3.1.1 Place the clothes washer in such a position that the uppermost edge of the clothes container opening is leveled horizontally, so that the container will hold the maximum amount of water. For front-loading clothes washers, the door seal and shipping bolts or other forms of bracing hardware to support the wash drum during shipping must remain in place during the capacity measurement.
  
  If the design of a front-loading clothes washer does not include shipping bolts or other forms of bracing hardware to support the wash drum during shipping, a laboratory may support the wash drum by other means, including temporary bracing or support beams. Any temporary bracing or support beams must keep the wash drum in a fixed position, relative to the geometry of the door and door seal components, that is representative of the position of the wash drum during normal operation. The method used must avoid damage to the unit that would affect the results of the energy and water testing. The test report must document the method used to support the wash drum, and pursuant to Sec. 429.71 of this chapter, the manufacturer must retain such documentation as part of its test records.
  
  3.1.2 Line the inside of the clothes container with a 2 mil thickness (0.051 mm) plastic sheet or plastic bag. All clothes washer components that occupy space within the clothes container and that are recommended for use during a wash cycle must be in place and must be lined with a 2 mil thickness (0.051 mm) plastic sheet or plastic bag to prevent water from entering any void space.

  3.2 Procedure for measuring water and energy consumption values on all automatic and semi-automatic washers. All energy consumption tests shall be performed under the energy test cycle(s), unless otherwise specified. Table 3.2 indicates the sections below that govern tests of particular clothes washers, based on the number of wash/rinse temperature selections available on the model and also, in some instances, method of water heating. The procedures prescribed are applicable regardless of a clothes washer's washing capacity, loading port location, primary axis of rotation of the clothes container, and type of control system. Data from a wash cycle that terminates prematurely if an out-of-balance condition is detected, and thus does not include the agitation/tumble operation, spin speed(s), wash times, and rinse times applicable to the wash cycle under test, shall be discarded.

  3. Test Measurements
  
  3.1 Clothes container capacity. Measure the entire volume that a clothes load could occupy within the clothes container during active mode washer operation according to the following procedures:
  
  Page 23091
  
  3.1.1 Place the clothes washer in such a position that the uppermost edge of the clothes container opening is leveled horizontally, so that the container will hold the maximum amount of water. For front-loading clothes washers, the door seal and shipping bolts or other forms of bracing hardware to support the wash drum during shipping must remain in place during the capacity measurement.
  
  If the design of a front-loading clothes washer does not include shipping bolts or other forms of bracing hardware to support the wash drum during shipping, a laboratory may support the wash drum by other means, including temporary bracing or support beams. Any temporary bracing or support beams must keep the wash drum in a fixed position, relative to the geometry of the door and door seal components, that is representative of the position of the wash drum during normal operation. The method used must avoid damage to the unit that would affect the results of the energy and water testing. The laboratory must fully document the method used to support the wash drum, include such documentation in the final test report, and pursuant to Sec. 429.71 of this chapter, the manufacturer must retain such documentation as part its test records.
  
  3.1.2 Line the inside of the clothes container with a 2 mil thickness (0.051 mm) plastic sheet or plastic bag. All clothes washer components that occupy space within the clothes container and that are recommended for use during a wash cycle must be in place and must be lined with a 2 mil thickness (0.051 mm) plastic sheet or plastic bag to prevent water from entering any void space.
  
  3.1.3 Record the total weight of the machine before adding water.
  
  3.1.4 Fill the clothes container manually with either 60 degF 5 degF (15.6 degC 2.8 degC) or 100 degF 10 degF (37.8 degC 5.5 degC) water, with the door open. For a top-loading vertical-axis clothes washer, fill the clothes container to the uppermost edge of the rotating portion, including any balance ring. Figure 3.1.4.1 of this appendix illustrates the maximum fill level for top-loading clothes washers.
  
  GRAPHIC TIFF OMITTED TP25AP14.027
  
  For a front-loading horizontal-axis clothes washer, fill the clothes container to the highest point of contact between the door and the door gasket. If any portion of the door or gasket would occupy the measured volume space when the door is closed, exclude from the measurement the volume that the door or gasket portion would occupy. For a front-loading horizontal-axis clothes washer with a concave door shape, include any additional volume above the plane defined by the highest point of contact between the door and the door gasket, if that area can be occupied by clothing during washer operation. For a top-loading horizontal-axis clothes washer, include any additional volume above the plane of the door hinge that clothing could occupy during washer operation. Figure 3.1.4.2 of this appendix illustrates the maximum fill volumes for all horizontal-axis clothes washer types.
  
  GRAPHIC TIFF OMITTED TP25AP14.028
  
  Page 23092
  
  For all clothes washers, exclude any volume that cannot be occupied by the clothing load during operation.
  
  3.1.5 Measure and record the weight of water, W, in pounds.
  
  3.1.6 Calculate the clothes container capacity as follows:
  
  C = W/d
  
  Where:
  
  C = Capacity in cubic feet (liters).
  
  W = Mass of water in pounds (kilograms).
  
  d = Density of water (62.0 lbs/ft\3\ for 100emsp14degF (993 kg/
  
  m\3\ for 37.8 degC) or 62.3 lbs/ft\3\ for 60emsp14degF (998 kg/m\3\ for 15.6 degC)).
  
  3.1.7 Calculate the clothes container capacity, C, to the nearest 0.01 cubic foot for the purpose of determining test load sizes per Table 5.1 of this appendix and for all subsequent calculations that include the clothes container capacity.
  
  3.2 Procedure for measuring water and energy consumption values on all automatic and semi-automatic washers.
  
  3.2.1 Perform all energy consumption tests under the energy test cycle.
  
  3.2.2 Perform the test sections listed in Table 3.2.2 in accordance with the wash/rinse temperature selections available in the energy test cycle.

  3.2.3.1 For automatic clothes washers, open both the hot and cold water faucets.
  
  3.2.3.2 For semi-automatic washers:
  
  (1) For hot inlet water temperature, open the hot water faucet completely and close the cold water faucet;
  
  (2) For warm inlet water temperature, open both hot and cold water faucets completely;
  
  (3) For cold inlet water temperature, close the hot water faucet and open the cold water faucet completely.
  
  3.2.4 Wash/rinse temperature selection. Set the wash/rinse temperature selection control to obtain the desired wash/rinse temperature selection within the energy test cycle.
  
  3.2.5 Wash time setting. If one wash time is prescribed for the wash cycle under test, that shall be the wash time setting; otherwise, the wash time setting shall be the higher of either the minimum or 70 percent of the maximum wash time available for the wash cycle under test, regardless of the labeling of suggested dial locations. If the clothes washer is equipped with an electromechanical dial controlling wash time, reset the dial to the minimum wash time and then turn it in the direction of increasing wash time to reach the appropriate setting. If the appropriate setting is passed, return the dial to the minimum wash time and then turn in the direction of increasing wash time until the appropriate setting is reached.
  
  3.2.6 Water fill levels.
  
  3.2.6.1 Clothes washers with manual water fill control system. Set the water fill selector to the maximum water level available for the maximum test load size and the minimum water level available for the minimum test load size.

  3.2.6.2.2 User adjustable. Conduct four tests on clothes washers with user adjustable automatic water fill controls that affect the relative wash water levels. Conduct the first test using the maximum test load and with the automatic water fill control system set in the setting that will give the most energy intensive result. Conduct the second test using the minimum test load and with the automatic water fill control system set in the setting that will give the least energy intensive result. Conduct the third test using the average test load and with the automatic water fill control system set in the setting that will give the most energy intensive result for the given test load. Conduct the fourth test using the average test load and with the automatic water fill control system set in the setting that will give the least energy intensive result for the given test load. Average the results of the third and fourth tests to obtain the energy and water consumption values for the average test load size.
  
  3.2.6.3 Clothes washers with automatic water fill control system and alternate manual water fill control system. If a clothes washer with an automatic water fill control system allows user selection of manual controls as an alternative, test both manual and automatic modes and, for each mode, calculate the energy consumption (HET, MET, and DE) and water consumption (QT) values as set forth in section 4 of this appendix. Then, calculate the average of the two values (one from each mode, automatic and manual) for each variable (HET, MET, DE, and QT) and use the average value for each variable in the final calculations in section 4 of this appendix.
  
  3.2.7 Manufacturer default settings. For all wash cycles tested, use the manufacturer default settings, except for (1) the temperature selection, (2) the wash water fill levels, or (3) if necessary, the spin speeds on wash cycles used to determine remaining moisture content. This includes wash conditions such as agitation/tumble operation, soil level, spin speed on wash cycles used to determine energy and water consumption, wash times, rinse times, optional rinse settings, water heating time for water heating clothes washers, and all other wash parameters or optional features applicable to that wash cycle. Include any optional wash cycle feature for testing (other than wash/rinse temperature, water fill level selection, or spin speed on wash cycles used to determine remaining moisture content) that is activated by default on the wash cycle under test unless the manufacturer instructions recommend not selecting this option for washing normally soiled cotton or linen clothes.
  
  3.2.8 For each wash cycle tested, include the entire active washing mode and exclude any delay start or cycle finished modes.
  
  3.2.9 Discard the data from a wash cycle that terminates prematurely if an out-of-balance condition is detected, and thus does not include the agitation/tumble operation, spin speed(s), wash times, and rinse times applicable to the wash cycle under test.

  6. Waivers and Field Testing
  
  6.1 Waivers and Field Testing for Nonconventional Clothes Washers. Manufacturers of nonconventional clothes washers, such as clothes washers with adaptive control systems, must submit a petition for waiver pursuant to 10 CFR 430.27 to establish an acceptable test procedure for that clothes washer if the washer cannot be tested pursuant to the DOE test procedure or the DOE test procedure yields results that are so unrepresentative of the clothes washer's true energy consumption characteristics as to provide materially inaccurate comparative data. In such cases, field testing may be appropriate for establishing an acceptable test procedure. The following are guidelines for field testing that may be used by manufacturers in support of petitions for waiver. These guidelines are not mandatory and the Department may determine that they do not apply to a particular model. Depending upon a manufacturer's approach for conducting field testing, additional data may be required. Manufacturers are encouraged to communicate with the Department prior to the commencement of field tests that may be used to support a petition for waiver. Section 6.3 of this appendix provides an example of
  
  Page 23098
  
  field testing for a clothes washer with an adaptive water fill control system. Other features, such as the use of various spin speed selections, could be the subject of field tests.
  
  6.2 Nonconventional Wash System Energy Consumption Test. The field test may consist of a minimum of 10 of the nonconventional clothes washers (``test clothes washers'') and 10 clothes washers already being distributed in commerce (``base clothes washers''). The tests should include a minimum of 50 wash cycles per clothes washer. The test clothes washers and base clothes washers should be identical in construction except for the controls or systems being tested. Equal numbers of both the test clothes washer and the base clothes washer should be tested simultaneously in comparable settings to minimize seasonal or end-user laundering conditions or variations. The clothes washers should be monitored in such a way as to accurately record the average total energy and water consumption per cycle, including water heating energy when electrically heated water is used, and the energy required to remove the remaining moisture of the test load. Standby and off mode energy consumption should be measured according to section 4.4 of this test procedure. The field test results should be used to determine the best method to correlate the rating of the test clothes washer to the rating of the base clothes washer.
  
  6.3 Adaptive water fill control system field test. (1) Section 3.2.6.3 of this appendix defines the test method for measuring energy consumption for clothes washers that incorporate both adaptive (automatic) and alternate manual water fill control systems. Energy consumption calculated by the method defined in section 3.2.6.3 of this appendix assumes the adaptive cycle will be used 50 percent of the time. This section can be used to develop field test data in support of a petition for waiver when it is believed that the adaptive cycle will be used more than 50 percent of the time. The field test sample size should be a minimum of 10 test clothes washers. The test clothes washers should be representative of the design, construction, and control system that will be placed in commerce. The duration of field testing in the user's house should be a minimum of 50 wash cycles, for each unit. No special instructions as to cycle selection or product usage should be given to the field test participants, other than inclusion of the product literature pack that would be shipped with all units, and instructions regarding filling out data collection forms, use of data collection equipment, or basic procedural methods. Prior to the test clothes washers being installed in the field test locations, baseline data should be developed for all field test units by conducting laboratory tests as defined by section 1 through section 5 of this appendix to determine the energy consumption, water consumption, and remaining moisture content values. The following data should be measured and recorded for each wash load during the test period: wash cycle selected, the mode of the clothes washer (adaptive or manual), clothes load dry weight (measured after the clothes washer and clothes dryer cycles are completed) in pounds, and type of articles in the clothes load (e.g., cottons, linens, permanent press). The wash cycles used in calculating the in-home percentage split between adaptive and manual cycle usage should be only those wash cycles that conform to the definition of the energy test cycle.
  
  Calculate:
  
  T = The total number of wash cycles run during the field test.
  
  Ta = The total number of adaptive control wash cycles.
  
  Tm = The total number of manual control wash cycles.
  
  The percentage weighting factors:
  
  Pa = (Ta/T) x 100% (the percentage weighting for adaptive control selection)
  
  Pm = (Tm/T) x 100% (the percentage weighting for manual control selection)
  
  (2) Energy consumption (HET, MET, and DE) and water consumption (QT) values calculated in section 4 of this appendix for the manual and adaptive modes should be combined using Pa and Pm as the weighting factors.

  8. Add a new Appendix J3 to subpart B of part 430 to read as follows:
  
  Appendix J3 to Subpart B of Part 430-Uniform Test Method for Measuring the Moisture Absorption and Retention Characteristics of New Energy Test Cloth Lots
  
  Note: DOE maintains an historical record of the standard extractor test data and final correctio5tn curve coefficients for each approved lot of energy test cloth. These can be accessed through DOE's Web page for standards and test procedures for residential clothes washers at DOE's Building Technologies Office Appliance and Equipment Standards Web site.
  
  1. Objective
  
  The following procedure is used to evaluate the moisture absorption and retention characteristics of a new lot of test cloth by measuring the remaining moisture content (RMC) in a standard extractor at a specified set of conditions. The results are used to develop a set of coefficients that correlate the measured RMC values of the new test cloth lot with a set of standard RMC values established as an historical reference point. These correction coefficients are applied to the RMC measurements performed during testing according to appendix J1 or appendix J2 to 10 CFR 430 subpart B, ensuring that the final corrected RMC measurement for a clothes washer remains independent of the test cloth lot used for testing.
  
  2. Definitions
  
  2.1 AHAM means the Association of Home Appliance Manufacturers.
  
  2.2 Bone-dry means a condition of a load of test cloth that has been dried in a dryer at maximum temperature for a minimum of 10 minutes, removed and weighed before cool down, and then dried again for 10 minute periods until the final weight change of the load is 1 percent or less.
  
  2.3 Lot means a quantity of cloth that has been manufactured with the same batches of cotton and polyester during one continuous process.
  
  3. Testing Conditions
  
  3.1 Table 3.1 of this appendix provides the matrix of test conditions. In the table, ``g Force'' represents units of gravitational acceleration. When this matrix is repeated 3 times, a total of 60 extractor RMC test runs are required. For the purpose of the extractor RMC test, the test cloths may be used for up to 60 test runs (after preconditioning as specified in appendix J1 or appendix J2).

  3.2 Perform the standard extractor RMC tests using a North Star Engineered Products Inc. (formerly Bock) Model 215 extractor (having a basket diameter of 20 inches, height of 11.5 inches, and volume of 2.09 ft\3\), with a variable speed drive (North Star Engineered Products, P.O. Box 5127, Toledo, OH 43611) or an equivalent extractor with same basket design (i.e. diameter, height, volume, and hole configuration) and variable speed drive. Table 3.2 shows the extractor spin speed, in revolutions per minute (RPM), that must be used to attain each required g-force level.

  3.3 Bone dryer temperature. The dryer used for bone drying must heat the test cloth and energy stuffer cloths above 210 degF (99 degC).
  
  4. Test Loads
  
  4.1 Preconditioning. New test cloths, including energy test cloths and energy stuffer cloths, must be pre-conditioned in a clothes washer in the following manner:
  
  Perform five complete wash-rinse-spin cycles, the first two with current AHAM Standard detergent Formula 3 and the last three without detergent. Place the test cloth in a clothes washer set at the maximum water level. Wash the load for ten minutes in soft water (17 ppm hardness or less) using 27.0 grams + 4.0 grams per pound of cloth load of AHAM Standard detergent Formula 3. The wash temperature is to be controlled to 135emsp14degF 5emsp14degF (57.2 degC 2.8 degC) and the rinse temperature is to be controlled to 60emsp14degF 5emsp14degF (15.6 degC 2.8 degC). Repeat the cycle with detergent and then repeat the cycle three additional times without detergent, bone drying the load between cycles (for a total of five complete wash-rinse-spin cycles).
  
  4.2 Test load composition. Test loads must be comprised of randomly selected cloth at the beginning, middle and end of a lot.
  
  4.3 Test load size. Use a test load size of 8.4 lbs. Two test loads may be used for standard extractor RMC tests, with each load used for half of the total number of required tests.
  
  5. Test Measurements
  
  5.1 Dry the test cloth until it is ``bone-dry'' according to the definition in section 2.2 of this appendix. Record the bone-dry weight of the test load (WI).
  
  5.2 Prepare the test load for soak by grouping four test cloths into loose bundles. Create the bundles by hanging four cloths vertically from one corner and loosely wrapping the test cloth onto itself to form the bundle. Bundles should be wrapped loosely to ensure consistency of water extraction. Then place the bundles into the water to soak. Eight to nine bundles will be formed depending on the test load. The ninth bundle may not equal four cloths but can incorporate energy stuffer cloths to help offset the size difference.
  
  5.3 Soak the test load for 20 minutes in 10 gallons of soft ( 5 degF (37.8 degC 2.8 degC) at all times between the start and end of the soak.
  
  5.4 Remove the test load and allow each of the test cloth bundles to drain over the water bath for a maximum of 5 seconds.
  
  5.5 Manually place the test cloth bundles in the basket of the extractor, distributing them evenly by eye. The draining and loading process must take no longer than 1 minute. Spin the load at a fixed speed corresponding to the intended centripetal acceleration level (measured in units of the acceleration of gravity, g) 1g for the intended time period 5 seconds. Begin the timer when the extractor meets the required spin speed for each test.
  
  5.6 Record the weight of the test load immediately after the completion of the extractor spin cycle (WC).
  
  5.7 Calculate the remaining moisture content of the test load as (WC-WI)/WI.
  
  5.8 Draining the soak tub is not necessary if the water bath is corrected for water level and temperature before the next extraction.
  
  5.9 Drying the test load in between extraction runs is not necessary. However, the bone dry weight must be checked after every 12 extraction runs to make sure the bone dry weight is within tolerance (8.4 0.1 lb).
  
  5.10 The test load must be soaked and extracted once following bone drying, before continuing with the remaining extraction runs. Perform this extraction at the same spin speed used for the extraction run prior to bone drying, for a time period of 4 minutes. Either warm or cold soak temperature may be used.
  
  5.11 Measure the remaining moisture content of the test load at five g levels: 100 g, 200 g, 350 g, 500 g, and 650 g, using two different spin times at each g level: 4 minutes and 15 minutes.
  
  5.12 Repeat sections 5.1 through 5.11 of this appendix using soft ( 5emsp14degF (15.6 degC 2.8 degC).
  
  6. Calculation of RMC Correction Curve
  
  6.1 Average the values of 3 test runs, and fill in Table 3.1 of this appendix. Perform a linear least-squares fit to determine coefficients A and B such that the standard RMC values shown in Table 6.1 of this appendix (RMCstandard) are linearly related to the RMC values measured in section 5 of this appendix (RMCcloth):
  
  RMCstandard ~ A * RMCcloth + B
  
  Where A and B are coefficients of the linear least-squares fit.

  6.2 Perform an analysis of variance with replication test using two factors, spin speed and lot, to check the interaction of speed and lot. Use the values from Table 3.1 and Table 6.1 of this appendix in the calculation. The ``P'' value of the F-statistic for interaction between spin speed and lot in the variance analysis must be greater than or equal to 0.1. If the ``P'' value is less than 0.1, the test cloth is unacceptable. ``P'' is a theoretically based measure of interaction based on an analysis of variance.
  
  7. Application of the RMC Correction Curve
  
  7.1 Using the coefficients A and B calculated in section 6.1 of this appendix:
  
  RMCcorr = A x RMC + B
  
  7.2 Apply this RMC correction curve to measured RMC values in appendix J1 and appendix J2.
