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.
This final rule is effective September 19, 2001.Start Further Info

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 Start Printed Page 48221amendment 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.Start List of Subjects
