SAE J 1113/4:2026-05-24

This SAE Recommended Practice 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 current from 1 to 400 MHz into the wiring harness of automotive devices. BCI is one of a number of test methods that can be used to simulate the electromagnetic field. For a list of others, see SAE J1113/1.
