scope:

Specifies bulk current injection (BCI) tests for the lectromagnetic immunity of electronic components of passenger cars and commercial vehicles, regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The electromagnetic disturbance considered in this part of ISO 11452 is limited to continuous narrowband electromagnetic fields. Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer, because, for example, of the hihg costs of an 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 is used by the manufacturer. ISO 11452-1 specifies general test methods, definitions, practical use and basic principles of the test procedure.
