ISO 11451-2:2015 specifies a method for testing the immunity of passenger cars and commercial vehicles to electrical disturbances from off-vehicle radiation sources, regardless of the vehicle propulsion system (e.g. spark ignition engine, diesel engine, electric motor). The electromagnetic disturbances considered are limited to narrowband electromagnetic fields.
