SAE J1113/12_202209

This SAE Standard establishes test methods for the evaluation of devices and equipment in vehicles against transient transmission by coupling via lines other than the power supply lines. The test methods demonstrates the immunity of the instrument, device, or equipment to coupled fast transient disturbances, such as those caused by switching of inductive loads, relay contact bouncing, etc. Four test methods are presented in SAE J1113-12: the capacitive coupling clamp (CCC) method the direct capacitive coupling (DCC) method the inductive coupling clamp (ICC) method the capacitive/inductive coupling (CIC) method The technical committee determines that the using community is moving towards newer technology and would like to alert users that this newer technology exists which may want to be considered for new design. However, because the technical committee has no complete visibility of where and how a technical report is being used, and because a technical report may be necessary to support legacy platforms or design reuse, the technical report should not be cancelled but rather stabilized with a rationale statement that alerts users to new technology. The EMC standards committee have determined that this standard contains similar documentation as ISO 7637-3 and also has the section 5.4 Transient Pulse Generator (the capacitive/inductive coupling (CIC) method). Because of the inclusion of 5.4, it is realized that the LD vehicle as a whole is moving away from mechanical switching devices and towards a newer technology of solid state switching devices. However, because the EMC standards committee sees it necessary to support legacy platforms or design reuse, SAE J1113-12 should not be cancelled but stabilized at this time.
