The April 1st, 2005 Global Technical Regulation (GTR) [ECE/TRANS/180/Add.1] Working Party for door locks and door retention components reviewed a combination loading static bench test for latch systems (combination test) that is capable of evaluating the strength of the latching systems and is designed to detect fork bolt detent bypass failures. In the combination test, the latch is mounted on a flat steel plate that moves horizontally. The striker is mounted on a vertically moving ram device. During the test, lateral tension of 6,650 N is applied and maintained on the coupled latch-striker system by moving the flat steel plate and then applying a longitudinal compressive force of 16,000 N by moving the striker at a constant rate.
