Road vehicles — Electrical disturbances from conduction and coupling — Part 3: Electrical transient transmission by capacitive and inductive coupling via lines other than supply lines - Second Edition
 N 7637-3

Annotation

This part of ISO 7637 establishes a common basis for the evaluation of the EMC of electronic instruments, devices and equipment in vehicles against transient transmission by coupling via lines other than the supply lines. The test intention is the demonstration of the immunity of the instrument, device or equipment when subjected to coupled fast transient disturbances, such as those caused by switching (switching of inductive loads, relay contact bounce, etc.).

In addition, severity levels are established, and the bench test procedures are described.

This part of ISO 7637 applies to all types of road vehicles fitted with a 12 V or 24 V electrical system, regardless of the propulsion system (e.g. spark-ignition or diesel engine, electric motor).

Failure mode severity classifications for immunity to transients are given in annex A.
