What are the standards for wire harness inspection? What are the specific standards? _Repeat

Harness inspection standards are the norms and standards that are followed in the inspection and testing of harnesses during the manufacturing process. Through the inspection can ensure that the quality of the harness, reliability and compliance with the specifications. The following are some common wiring harness inspection standards: 1. IPC/WHMA-A-620: IPC/WHMA-A-620 is by the IPC (International Electronics Association) and WHMA (Wiring Harness Manufacturers Association) jointly developed by the wiring harness manufacturing standards. The standard specifies the requirements for the appearance, size, insulation, wire installation and terminal processing of wire harnesses, and provides methods of inspection and testing.2. UL 1581: UL 1581 is a standard for wire harness materials developed by UL (Underwriters Laboratories). The standard covers the performance requirements of various harness components such as wires, insulation materials and sheath materials, including electrical properties, mechanical properties, heat resistance, etc. 3. ISO 6722: ISO 6722 is a standard for automotive wiring harnesses developed by the International Organization for Standardization (ISO). The standard specifies the electrical performance of automotive wiring harnesses, temperature range, flame retardant properties and other requirements, and provides a test method and classification of wiring harnesses.4. SAE J1939: SAE J1939 is developed by the American Society of Automotive Engineers (SAE) used in commercial vehicles for the wiring harness communication protocol standard. The standard specifies the electrical characteristics of the harness in the communication system, communication protocols and physical connection requirements.5. MIL-STD-202: MIL-STD-202 is the U.S. Department of Defense developed standards for wiring harnesses in military equipment. The standard specifies test methods and requirements for wiring harnesses in terms of mechanical, environmental and electrical aspects. In addition to the standards listed above, there are many industry and application-specific standards and specifications for areas such as aerospace, medical devices, and industrial automation. These standards are usually tailored to specific industry needs and application requirements, providing the appropriate test methods and requirements to ensure the quality and reliability of the wiring harness. In practice, the appropriate standards are selected for inspection and testing of wire harnesses based on specific industry and application needs.
