What is ISO 6469-3 about?

ISO 6469-3 is part three of the multi-series standard that 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.

ISO 6469-3 specifies electrical safety requirements for protection of persons against electric shock and thermal incidents.

Note-

ISO 6469-3 does not provide comprehensive safety information for manufacturing, maintenance and repair personnel.

Who is ISO 6469-3 for?

ISO 6469-3 on electrical safety of electrically propelled road vehicles is useful for:

• Electric vehicle manufacturers
• Electric vehicle components manufacturers
• Vehicle regulatory authorities
• Vehicle repair shops

Why should you use ISO 6469-3?

An electric vehicle consists of a battery with a large amount of energy stored in it. The electrical safety of the vehicle is thus very important. Any incident can be fatal.

ISO 6469-3 specifies electrical safety requirements for protection of persons against electric shock and thermal incidents.

ISO 6469-3 provides safety requirements for protection against thermal incidents which can occur due to overload and short circuit protection.

ISO 6469-3 gives test to demonstrate the adequacy of the protection measures to isolate live parts of voltage class B electric circuits. This will help the vehicle withstand voltage.

ISO 6469-3 lays out requirements for protective barriers and protective enclosures which will provide insulation from electrically charged components.

What’s changed since the last update?

BS ISO 6469-3:2021 is the fourth edition that cancels and replaces the third edition (ISO 6469-3:2018), which has been technically revised. It also incorporates the Amendment ISO 6469-3:2018/Amd.1:2020.

The main changes are as follows:

• Changes from ISO 6469-3:2018/Amd.1:2020 were implemented
• Requirements for equipotential bonding were revised
