Title:Moving Rigid Barrier Collision Tests
Issuing Committee:Impact And Rollover Test Proced Stds Comm
Scope: Collision tests are conducted on automotive vehicles to obtain information of value in evaluation of structural integrity and in reducing occupant injuries. The deformation resulting from a moving rigid barrier impact is more severe at a given speed than that produced by using a crushable vehicle, but is more readily reproducible than that occurring during impacts of two vehicles. The purpose of this recommended practice is to establish sufficient standardization of moving barriers and moving barrier collision methods so that results of tests conducted at different facilities may be compared. Background information and a rationale for the test procedures described in this recommended practice are provided in the Appendix.
