This SAE Standard defines a method for evaluating the immunity of automotive electrical/electronic devices to radiated electromagnetic fields coupled to the vehicle wiring harness. The method, called Bulk Current Injection (BCI), uses a current probe to inject RF onto the wiring harness in the frequency range of 1 to 400 MHz. BCI is one of a number of test methods that can be used to simulate the electromagnetic field.
The test method is being revised to reflect the latest changes in the corresponding international standard (ISO 11452-4). The equation for calculating the threshold of induced current based on measured calibration power for the substitution test method is also added. The preferred test method (Substitution Method) is listed before the alternate test method (Closed Loop Method). Appendix A, Function Performance Status Classification (FPSC), is also revised to included latest changes in SAE J1812, SAE J1113-1 and ISO 11452-4. Additional examples for applications of FPSC are also incorporated in Appendix A.
