Anthropomorphic Test Devices; SID-IIs Side Impact Crash Test Dummy; 5th Percentile Adult Female

This final rule responds to petitions for reconsideration of a December 14, 2006 final rule establishing a new small adult female side impact crash test dummy, called the "SID-IIs" test dummy. The petitions were submitted by the Alliance of Automobile Manufacturers, First Technology Safety Systems, and Denton ATD. In response to the petitions, among other things today's final rule modifies the iliac performance criteria to allow a new material formulation and design to be used for the iliac wing of the dummy's pelvis, defines a time period in which accelerations are measured in the thorax with arm and pelvis acetabulum tests, slightly modifies some of the test procedures used in the qualification tests (e.g., by slightly lowering the impact speed of the impactor in two tests and by increasing the recovery time for the pelvis-iliac and pelvis-acetabulum tests), adjusts the performance corridors for the various impact tests of the dummy, and revises parts of the drawing package and the user's manual for the dummy.
