RIN 2127-AH24
Federal Motor Vehicle Safety Standards; Occupant Crash Protection; Correction
AGENCY: National Highway Traffic Safety Administration (NHTSA); Department of Transportation.
ACTION: Correcting amendments.
SUMMARY: This rule corrects an error in the neck injury criteria that are specified for the alternative unbelted sled test included in our occupant protection standard. We revised certain of the neck injury criteria in a final rule; correcting amendment published in the Federal Register (63 FR 71390) on December 28, 1998. However, we have become aware that, as a result of that final rule; correcting amendment, portions of the neck injury criteria that were not revised were inadvertently deleted from the standard as published in the Code of Federal Regulations. This document reinstates the inadvertently deleted criteria.
DATES: This final rule is effective September 19, 2001.
FOR FURTHER INFORMATION CONTACT: For non-legal issues, you may contact Dr. Roger A. Saul, Director, Office of Crashworthiness Standards, NPS- 10. Telephone: (202) 366-1740. Fax: (202) 493-2739. E-mail: Roger.Saul@NHTSA.dot.gov.
For legal issues, you may contact Edward Glancy or Rebecca MacPherson, Office of Chief Counsel, NCC-20. Telephone: (202) 366-2992. Fax: (202) 366-3820.
You may send mail to these officials at the National Highway Traffic Safety Administration, 400 Seventh St., SW, Washington, DC, 20590.
SUPPLEMENTARY INFORMATION: Standard No. 208, Occupant Crash Protection, includes among its requirements certain neck injury criteria for the unbelted sled test. On December 28, 1998, we published in the Federal Register (63 FR 71390) a final rule; correcting
[[Page 48221]]
amendment that, among other things, clarified that two of the neck injury criteria, flexion bending moment and extension bending moment, are calculated at the occipital condyle. We have become aware that, as a result of that final rule; correcting amendment, the three other neck injury criteria, axial tension, axial compression, and fore-and-aft shear, were inadvertently deleted from the standard as published in the Code of Federal Regulations. This document reinstates the inadvertently deleted criteria.
