What are the standards for wire harness crimping? What are the specific standards?

Harness crimping is a common connection technique used to secure the contact between wires and cables and connectors. The quality and reliability of the harness crimp directly affects the performance and electrical conductivity of the connection. The following are some common standards and requirements for wiring harness crimping: IPC/WHMA-A-620: IPC/WHMA-A-620 is a wiring harness assembly standard jointly developed by the International Electronics Industry Confederation (IPC) and the Wire Harness Manufacturers Association (WHMA). The standard covers all aspects of wiring harness crimping, including crimping terms and definitions, material selection, crimping operation requirements, connector quality assessment, etc. UL 486A-486B: UL 486A-486B is a series of standards developed by the U.S. safety certification body Underwriters Laboratories (UL), covering the assessment of wire and cable connectors requirements. These include requirements for crimp connectors for wire harnesses, including requirements for wire size, crimp strength, electrical performance, vibration and shock resistance, etc. DIN 46228-1: DIN 46228-1 is a standard developed by the German Industrial Standardization Organization (DIN) covering crimp connections in electrical connection technology. The standard describes in detail the operation method of crimping connection, dimensional requirements of crimping connector, crimping strength and electrical performance testing after crimping, etc. MIL-STD-202: MIL-STD-202 is a U.S. military standard for reliability and environmental resistance testing of electronic components and equipment. It includes test methods and requirements for wire harness crimping, such as crimp strength, contact resistance, vibration and shock, and other environmental tests. iso 9001: iso 9001 is an international standard that deals with the requirements of quality management system. In the field of wire harness crimping, ISO 9001-compliant companies should have an appropriate quality management system in place and ensure that their crimping operations comply with the specified requirements and standards. These standards and requirements are designed to ensure the quality and reliability of wire harness crimping to provide a stable electrical connection. They cover all aspects of harness crimping, including operational procedures, connector selection, crimp strength, electrical performance testing, environmental suitability, and more. Compliance with these standards for wire harness crimping operations ensures a reliable, durable, and consistent connection that meets the requirements of equipment manufacturers and customers, and ensures the safe and reliable operation of the equipment.
