What are the codes and standards for the automotive wiring harness industry?

An automotive wiring harness is a collection of wires and connectors that connect various electrical devices inside a vehicle. In the automotive wiring harness industry, there exists a series of codes and standards that are designed to ensure the safety, reliability and interoperability of automotive wiring harnesses. The following are some common automotive wiring harness codes and standards: ISO 6722: This is an automotive wire specification developed by the International Organization for Standardization (ISO). It specifies the electrical characteristics, insulation materials, temperature ratings and test methods for automotive wiring harnesses.SAE J1128: Automotive wiring specification developed by the Society of Automotive Engineers (SAE). It defines the electrical characteristics, insulation materials, color codes, and test methods for automotive wiring harnesses.SAE J1939: This is a Controller Area Network (CAN) communication protocol standard for commercial vehicles. It defines the data communication format and network management used in commercial vehicles. IPC/WHMA-A-620: A standard for wiring harness assembly developed by the International Electronics Industry Consortium (IPC) and the Wire Harness Manufacturers Association (WHMA). It defines the design, manufacturing and testing requirements for wire harnesses.GMW3172: Wire harness validation specification developed by General Motors. It specifies the verification process, test methods and acceptance criteria for wiring harnesses. UL 758: Standard for wire insulation materials issued by the United States Safety Laboratory (UL). It specifies the physical, electrical and environmental performance requirements of wire insulation materials. DIN 72551: German Industrial Standardization Organization (DIN) issued by the automotive wiring harness standard. It specifies the color code, electrical characteristics and test methods for wire harnesses.JASO D 611: Standard for wire harnesses issued by the Japan Automotive Standards Organization (JASO). It specifies the physical characteristics, electrical characteristics and environmental test requirements of wiring harnesses. IEC 60529: International Electrotechnical Commission (IEC) issued by the International Electrotechnical Commission (IEC) of the international protection level standard. It specifies the protection level of electrical equipment, including the waterproof and dustproof capability of wiring harness connectors.VDA 4700: The wiring harness design and manufacturing guidelines developed by the German Association of the Automotive Industry (VDA). It provides recommendations for wiring harness design, processes and quality management. These codes and standards cover the design, manufacture, testing, color coding, physical properties, electrical properties, environmental testing and safety requirements for wiring harnesses. Compliance with these codes and standards ensures that the quality and performance of automotive wiring harnesses meets internationally recognized standards, thereby improving the safety, reliability and interoperability of automobiles.
