What are the automotive wiring harness tests? How to test automotive wiring harness?

An automotive wiring harness is a collection of wires and connectors that connect electrical devices throughout the vehicle. The quality of the wiring harness directly affects the safety and reliability of the entire vehicle. Therefore, in the production process, the need for automotive wiring harnesses for rigorous testing to ensure that its quality meets the standards. First, the automotive wiring harness test project 1. conduction test conduction test refers to the wiring harness conduction performance test, through the conduction test can be found in the line whether there is poor contact, disconnection, short-circuit and other issues. Usually use a multimeter to carry out the test. 2. insulation test insulation test is to test the insulation performance of the wiring harness, through the insulation test can be found in the line whether there is leakage. Usually use insulation resistance tester to carry out the test. 3. voltage resistance test voltage resistance test is the wiring harness to test the ability to withstand pressure, through the voltage resistance test can be found whether the line can withstand the rated voltage test. Usually use a high voltage tester to test. 4. waterproof test waterproof test is the harness waterproof performance test, through the waterproof test can be found whether the line has water seepage, water leakage and other issues. Usually spray test, immersion test and other methods of testing. 5. anti-interference test anti-interference test is the harness of the anti-interference ability to test, through the anti-interference test can be found through the line is able to withstand interference from other electronic equipment. Usually use analog signal interference and other methods of testing.6. Mechanical Performance TestMechanical performance test is the mechanical strength of the wiring harness, durability and other performance tests, through the mechanical properties of the test can be found through the line whether it can withstand the daily use of tensile, bending, vibration and other efforts. Usually use tensile test, bending test, vibration test and other methods of testing.7. Weathering test weathering test is the harness weathering performance test, through the weathering test can be found through the line can withstand high temperature, low temperature, ultraviolet and other climatic conditions under the use of the test. Usually high temperature aging test, low temperature aging test, ultraviolet aging test and other methods of testing. Second, the automotive wiring harness test method 1. manual inspection method manual inspection method is a traditional wiring harness test method, usually carried out by specialized quality control personnel, through visual and manual inspection of the quality of the wiring harness is in line with the standard. 2. instrumentation testing method instrumentation testing method is a modern wiring harness test method, the use of a variety of instruments on the wiring harness of the various properties of testing.
