Electrical tests, EMC and ESD

EMC testing – Measurements of emissions of conductive interference in accordance with ISO 7637-2*

Test aim

The electrical and electronic equipment present in a vehicle, connected in many cases by means of long wiring harnesses, with a large number of connections, may experience mutual interference with each other through electrical interference transmitted by conduction along the power cables. In order to determine the nature and level of the interference, tests of emitted conductive interference are carried out.

*standard referred to in UNECE Regulation No. 10.
