This document specifies electrical safety requirements for voltage class B electric circuits of electric propulsion systems and conductively connected auxiliary electric systems of electrically propelled road vehicles. It specifies electrical safety requirements for protection of persons against electric shock and thermal incidents . This third edition cancels and replaces the second edition (ISO 6469-3:2011), which has been technically revised. The main changes compared to the previous edition are as follows: · — extension of pure electric shock protection to all electric safety requirements including those against thermal incidents; · — introduction of definitions and requirements for new voltage classes B1 and B2; · — addition of specific requirements for capacitive discharge; · — new test specification for the isolation resistance monitoring system; and · — new requirements and test for touch current.
