scope:

Specifies test methods and procedures for testing electromagnetic immunity (off-vehicle radiation sources) of electronic components for passenger cars and commercial vehicles regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). To perform this test method, the electronic module along with the wiring harness (prototype or standard test harness) and peripheral devices are subjected to the electromagnetic disturbance generated inside an absorberlined chamber. The electromagnetic disturbances considered in this part of ISO 11452 are limited to continuous narrowband electromagnetic fields. Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer. The reasons, for example, are the high costs of an absorber-lined chamber, preserving the secrey of prototypes, or the large number of different vehicle models. Therefore, for research, development and quality control, a laboratory measuring method is used by the manufacturer. Part 1 of ISO 11452 gives general information, definitions, practical use and basic principles of the test procedure.
