Harness testing standards and requirements are to ensure that the quality, reliability and performance of the harness meet the specified requirements. The following are some common harness testing standards and requirements: 1. Electrical testing: Electrical testing is an important part of harness testing, which is used to verify the electrical connection and performance of the harness. This includes testing the harness for continuity, insulation resistance, resistance, capacitance, inductance, power, and other parameters. 2.Lead test: Lead test is a test to verify the correctness and connectivity of the harness leads. Ensure that the harness is properly connected to the appropriate devices and interfaces by checking the location, connections, and identification of each lead. 3. Environmental test: The harness is usually used in various environmental conditions, so environmental test is required to ensure the reliability of the harness in different temperature, humidity, vibration and other environments. This includes high temperature testing, low temperature testing, damp heat cycling testing, vibration testing, etc. 4. Durability test: The durability test is used to evaluate the durability and reliability of the harness during long-term use. Check the mechanical strength and connection performance of the harness by simulating the bending, stretching, plugging and unplugging of the harness. 5. Chemical resistance test: The chemical resistance test is used to evaluate the resistance of the harness to chemical substances. Check the resistance of the material of the wire harness to different chemicals, solvents or lubricants by exposing the wire harness to these substances. 6. Fire performance test: The fire performance test is used to evaluate the combustion performance and flame retardant performance of the wiring harness in case of fire. Ensure that the wiring harness meets the relevant fire protection standards by conducting flame propagation test, combustion test and self-extinguishing test. 7.Dimensional and visual inspection: Dimensional and visual inspection is the basic requirement in the harness test. Check the length, width, thickness and appearance quality of the harness to ensure that the size and appearance of the harness in the manufacturing process meet the requirements. There may be specific test standards and requirements for different industries and applications. For example, wire harness testing in the automotive industry may be required to comply with automotive manufacturer specifications and standards, and wire harness testing in the aerospace industry may be required to comply with relevant aerospace standards. When testing the wiring harness, the following steps are usually used: 1. Design the test plan: According to the specifications and requirements of the wiring harness, formulate the corresponding test plan, including the selection of test methods, test parameters and test equipment. 2. Prepare the test environment: according to the test requirements, prepare the appropriate test environment, including temperature, humidity and vibration. 3.Perform electrical tests: Use appropriate test equipment to perform electrical tests on the harness, including continuity tests, insulation tests, resistance tests, and capacitance tests. 4.Conduct the lead test: check the lead position, connection and identification of the harness to ensure that the harness is correctly connected to the corresponding equipment and interface. 5. Environmental test: according to the test requirements, the harness is exposed to different environmental conditions for high temperature test, low temperature test, damp heat cycle test and vibration test. 6. Conduct durability test: simulate the operation of the harness in actual use, conduct bending, stretching and plugging tests, and evaluate the mechanical strength and connection performance of the harness. 7.Conduct chemical resistance test: Expose the wire harness to different chemicals to check the resistance and chemical stability of the wire harness material. 8. Conduct fire performance test: conduct flame propagation test, combustion test and self-extinguishing test to evaluate the fire performance and combustion performance of the wiring harness. 9.Size and appearance inspection: check the size, appearance quality and identification of the harness to ensure that the size and appearance of the harness in the manufacturing process meet the requirements. 10.Record and analyze the test results: Record the test data and results, and analyze and evaluate the data to determine whether the harness meets the specified standards and requirements. Wiring harness testing needs to strictly follow the relevant test standards and requirements to ensure that the quality, reliability and performance of the wiring harness meet the specified standards, so as to ensure the normal operation and safety of the wiring harness in practical applications.
