This part of SAE J1113 specifies the direct RF power injection test method and procedure for testing electromagnetic immunity of electronic components for passenger cars and commercial vehicles. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous, narrowband conducted RF energy. This test method is applicable to all DUT leads except ground. The test provides differential mode excitation to the DUT. Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer. The reasons, for example, are high costs of a large absorber-lined chamber, preserving the secrecy of prototypes or the large number of different vehicle models. Therefore, for research, development, and quality control, a laboratory measuring method for components shall be applied by the manufacturer. This method is suitable over the frequency range of 250 kHz to 500 MHz.

The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous, narrowband conducted RF energy. This test method is applicable to all DUT leads except the RF reference ground. The test provides differential mode excitation to the DUT. Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer. The reasons, for example, are high costs of a large absorber-lined chamber, preserving the secrecy of prototypes or the large number of different vehicle models. Therefore, for research, development, and quality control, a laboratory measuring method for components shall be applied by the manufacturer. This method is suitable over the frequency range of 250 kHz to 400 MHz.

This SAE Standard provides a general method for defining the function performance status classification for the functions of automotive electronic devices upon application of the test conditions specified as described in appropriate EMC test standards (for example, SAE J1113 & SAE J551). Testing of devices could be performed either on or off vehicles. Appropriate test signal and methods, Function Performance status, and test signal severity level would have to be specified in the individual cases.
