Scope: This life test for underhood/passenger/trunk connector systems may be used in place of Section 5.8.6 (Connector System Electrical Test Flow Chart) of SAE/USCAR-2. All other requirements of SAE/USCAR-2 remain applicable even when this test is used. Refer to SAE/USCAR-2 and Connector/Terminal Supplier for appropriate power rating and current cycle Testing. When this life test is used in place of para. 5.8.6 of USCAR-2@ complete Para 5.6.1 (Thermal Shock) of SAE/USCAR-2 in it's entirety in order to demonstrate capability to withstand the 10-cycle service (mate/un-mate) requirement. This test specification details the procedure for testing the performance of electrical connections to a test sequence (FCLT ?C Field Correlated Life Test) that has been correlated to automotive vehicle conditions. The correlation applies to crimps and interfaces used in automotive applications and has been established with thousands of samples and millions of product and vehicle environmental measurements. The testing is performed with mated connector assemblies. In general@ testing of connections at two base temperatures@ 85??and 125?? through two cycles of the FCLT has been shown to correlate to at least 150@000 miles (240@000 kilometers). See Reference Documentation section for questions regarding correlation issues.
