Product Code:SAE J367
Title:Passenger Car Door System Crush Test Procedure (Cancelled Feb 2003)
Issuing Committee:Impact And Rollover Test Proced Stds Comm
Scope:This SAE Recommended Practice establishes a uniform laboratory test method to evaluate the capability of passenger car door systems to resist a concentrated lateral inward load. The procedure is intended to provide repeatable results and to permit numerical comparisons.A test is conducted in which the door and related structural members of the vehicle are loaded under controlled laboratory conditions. Structural strength measurements obtained under these conditions are reproducible. Background information and rationale for the test procedures described in this Recommended Practice are provided in the Appendix.
