This part of ISO 11452 specifies stripline tests for determining the immunity of electronic components for passenger cars and commercial vehicles to electrical distrubances from narrowband electromagnetic energy, regardless of the vehicle propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). As the performance of these tests depends on the exposure of the equipment harness to a disturbance field, the applicability of this part of ISO 11452 is limited to equipment harnesses, which have a maximum diameter of one-third the stripline height or less.

The electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields.
