What is ISO 20076 - Voltage class B connectors about?
ISO 20076 is the international standard on road vehicles that discusses the test specification that is unique to high voltage connectors. It defines terms and specifies test methods for general performance requirements of voltage class B connectors with single-pole and multi-pole connections used with electrical wiring harnesses of road vehicles.
ISO 20076 applies to connectors for voltage class B electric circuits of electric propulsion systems and conductively connected auxiliary electric systems of electrically-propelled road vehicles. It also applies to voltage class B connectors designed to be disconnected after mounting in the vehicle for repair and maintenance only.
ISO 20076 applies to cable conductor sizes ranging from 1,5 mm2 to 120mm2.
NOTE 1: ISO 20076 does not apply to vehicle inlets of charging systems.
NOTE 2: ISO 20076 is not applicable to internal connections of electronic devices.
Who is ISO 20076 - Voltage class B connectors for?
ISO 20076 on voltage class B connectors of road vehicles is useful for:
- Road vehicle designers and manufacturers
- Mechanical engineers
- Manufacturers of electric connectors
Why should you use ISO 20076 - Voltage class B connectors?
The voltage class B connectors are an assembly of the terminal, housing, and related parts that terminate cable and shielding for the purpose of providing connection and disconnection to a suitable mating connector.
ISO 20076 provides guidance regarding the test and requirements on connectors for preconditioning environmental and mechanical durability.
ISO 20076 help you in carrying out a visual examination of all connectors and contacts with the naked eye, at normal strength of vision and colour perception at the most favourable viewing distance.
ISO 20076 explains the test preconditions of the connector for further tests by being subjected to multiple connections and disconnections.
Testing tensile strength for connections which is used to determine capability for mechanical robustness is mentioned in ISO 20076.
ISO 20076 navigates you through the oil and liquid resistance test to evaluate the sealing capability and material compatibility of a connector system when exposed to various fluids. Moreover, ISO 20076 can assist you in designing voltage class B connectors for road vehicles.
With compliance with ISO 20076, you can determine the serviceability of the design and ensure that the connection will stay mated for the service life of the vehicle. In this manner, you ensure the quality and suitability of the chosen insulation system.
