This part of ISO 7637 specifies bench tests for testing the compatibility to conducted electrical transients of

equipment installed on passenger cars and light commercial vehicles fitted with a 12 V electrical system or

commercial vehicles fitted with a 24 V electrical system — for both injection and the measurement of

types of road vehicle, independent of the propulsion system (e.g. spark ignition or diesel engine, or electric
