What is the standard for wire harness terminal crimping?

A crimp standard for wire harness terminals is a specification used to ensure a reliable connection between a wire harness and a terminal. These standards are usually developed by relevant industry organizations, manufacturers or standards bodies and are designed to ensure the quality, reliability and safety of the connection. Below are some common wire harness terminal crimp standards that can help ensure a good connection.
Standard Documents and Specifications: Wire harness terminal crimping standards are usually defined in relevant standard documents and specifications. These documents may include standards, industry standards, manufacturer specifications, or international standards. For example, the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE) have both published a number of standards and specifications related to wire harness terminal crimping.
Terminal Sizes and Materials: Standards typically specify the size range and material requirements for wire harness terminals. These size and material requirements are determined based on current loads, environmental conditions, and other factors. The size and material selection of the terminal must comply with the relevant standards to ensure the reliability and safety of the connection.
Crimping Tools and Equipment: Standards may also address requirements for crimping tools and equipment. These requirements may include the type of crimping tool, specifications, calibration requirements and maintenance guidelines. Proper selection and use of the proper crimping tools and equipment is critical to achieving consistent crimp quality.
Crimp Parameters: Standards may also define crimp parameters such as crimp force, crimp time, and crimp depth. These parameters are designed to ensure that sufficient force is provided during the crimping process to form a reliable electrical connection, and must be adjusted to the characteristics of the wire harness and terminal.
Crimp Inspection and Testing: Standards typically require inspection and testing of crimped connections to verify the quality and reliability of the connection. These tests may include the use of conductivity testers, tension tests, vibration and shock resistance tests, etc. Inspection and testing of crimp connections ensures that the connection meets the requirements of the standard and will function properly under a variety of conditions.
Documentation and identification: The standard may also require documentation of information related to the crimped connection, such as date, operator, crimp parameters and test results. These records are important for traceability and quality management. In addition, the standard may require that crimped harness terminals be identified so that they can be accurately determined during subsequent maintenance and troubleshooting.
