scope:

This Standard applies to electric and electronic components used for electrically propelled road vehicles. It applies to components including electric power sources and loads connected to voltage class B electric circuit of an electric propulsion system. The standard focuses on the behaviour at the d.c. voltage class B terminals of these components.

The standard describes testing methods, test conditions and test requirements for components exposed to electrical behaviour at a d.c. voltage class B electric circuit, caused by operation of electric loads and power sources.

This standard does not cover electrical safety (see ISO 6469, ISO 17409).
