scope:

Specifies tests for electromagnetic immunity 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, the equipment harness is exposed to a disturbance field. This technique is limited to equipment harnesses which have a maximum diameter one-third the stripline height or less. The electromagnetic disturbances considered in this part are limited to continuous narrowband electromagnetic fields. Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer because, for example, of the high costs of an absorber-lined room, preserving the secrecy of prototypes or the large number of vehicle models. Therefore, for research, development and quality control, a laboratory measuring method is used by the manufacturer. ISO 11452-1 specifies general test methods, definitions, practical use and basic principles of the test procedure.
