SID-IIs Test Dummy

On June 23, 2009, NHTSA published a final rule that responds to petitions for reconsideration of a December 14, 2006 final rule establishing a new small adult female side impact crash dummy (SID-IIs). Among other things, the 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), adjust 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.
