ISO 6469-3:2011
Electrically propelled road vehicles — Safety specifications — Part 3: Protection of persons against electric shock
ISO 6469-3:2011 specifies requirements for the electric propulsion systems and conductively connected auxiliary electric systems, if any, of electrically propelled road vehicles for the protection of persons inside and outside the vehicle against electric shock.
ISO 6469-3:2011 does not apply to motorcycles and vehicles not primarily intended as road vehicles, such as material handling trucks or forklifts.
ISO 6469-3:2011 applies only to on-board electric circuits with maximum working voltages according to voltage class B.
ISO 6469-3:2011 does not provide comprehensive safety information for manufacturing, maintenance and repair personnel.
