SAE J1113 specifies test methods and procedures for the testing of electromagnetic immunity of electronic components for passenger cars and commercial vehicles. To perform this test method, the electronic module along with the wiring harness (prototype or standard test harness) and peripheral devices will be subjected to the electromagnetic disturbance generated inside an absorber-lined chamber. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous narrowband electromagnetic fields.
Immunity measurements for SAE J1113 of complete vehicles are generally only performed at the vehicle manufacturer. The reasons include high costs of a large absorber-lined chamber, preserving the secrecy of prototypes, or a large number of different vehicle models. Therefore, a laboratory measuring method shall be applied by the manufacturers for research, development, and quality control purposes.
