This part of ISO 11451 specifies bulk current injection (BCI) test methods for testing the 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). The electromagnetic disturbance considered in this part of ISO 11451 is limited to continuous narrowband electromagnetic fields.

ISO 11451-1 gives definitions, practical use and basic principles of the test methods.
