This document specifies test methods and procedures to ensure the compatibility to conductedelectrical transients along shielded high voltage supply lines of equipment installed on passenger carsand commercial vehicles fitted with electrical systems with voltages higher than 60 V d.c. and lowerthan 1 500 V d.c. and a power supply isolated from the vehicle body. It describes bench tests for both,injection and measurement of transients. It is applicable to all types of electrical independent driven,road vehicles (e.g. battery electrical vehicle (BEV) or hybrid electrical vehicle (HEV), plugin hybridelectric vehicle (PHEV)).
