Offset Barrier Crash Test Protocol (Version X) Document Revision History

differs from Version IX in that the driver dummy seat positioning follows the Guidelines for Using the UMTRI ATD Positioning Procedure for ATD and Seat Positioning (Version III) instead of placing the driver seat in the midtrack full-down position. Version IX differs from Version VIII in two ways: Underbody photography, underbody deformation measurements, and rotating the test vehicle onto its passenger side to check for postcrash fuel spillage and to photograph the overhead view are all eliminated; and Prior to the offset barrier crash test, test vehicles are subject to a frontal impact at 5 mi/h (8 km/h) into either a flat barrier or an angle barrier (formerly angle barrier only). Version VIII, in turn, is a minor revision of Version VII. Version VIII includes: A procedure for adjusting the test weight of the vehicle to fall within specific limits relative to its measured curb weight; An explanation of the conditions under which passenger doors are locked or unlocked prior to the test; A description of the backup impact speed measurement device
