National Highway Traffic Safety Administration June 16, 2008 – Federal Register Recent Federal Regulation Documents

This final rule responds to petitions for reconsideration of a December 6, 2006 final rule establishing in 49 CFR part 572 a new mid- size adult male side crash test dummy, called the ``ES-2re'' test dummy. The petitions were submitted by the Alliance of Automobile Manufacturers, First Technology Safety Systems, and Denton ATD. In response to the petitions, this document slightly revises the specifications for conducting the neck assembly qualification test, narrows the tolerances for the tuning spring rates for the dummy's thorax, revises performance corridors for the full body thorax test, corrects cross-references in the Part 572 regulatory text and makes minor changes to the drawing package and user's manual for the test dummy.
