What are the aspects of wire harness inspection? What are the requirements and standards for wire harness inspection?

Wiring harness testing usually includes the following aspects: 1. Connection testing: testing the electrical connectivity of each connection point in the harness to ensure the correct transmission of signals and power. This can be accomplished by using test equipment to conduct resistance, voltage, current, etc. 2. Insulation testing: testing the insulation properties in the harness to prevent short circuits and leakage. This involves insulation resistance testing of the harness using insulation resistance testing instruments to ensure the quality of the insulation layer.3. Voltage testing: Detects the ability of the harness to withstand high voltage conditions to ensure that the harness does not break down within the operating voltage range. This is usually carried out using a high voltage test instrument to detect the insulation and voltage resistance of the harness.4. Short circuit test: Detect whether there is a short circuit in the harness to prevent signal interference or equipment damage. A short circuit test can be performed using a short circuit test instrument on the wiring harness to detect whether there is a short circuit between the wires.5. Overload test: Detects the performance of the wiring harness under rated load conditions to ensure that the wiring harness can normally withstand the rated current and remain stable. This can be accomplished by applying a rated load to the harness and conducting a current test.6. Bend Test: Detects the durability and reliability of the harness under bending or twisting conditions. This can be accomplished by applying a bending or twisting load to the harness and observing the deformation of the harness to evaluate its performance. The requirements and standards for wire harness testing can vary depending on the industry and application. Generally speaking, the following are some common requirements and standards: 1. Compliance with relevant safety standards: the wiring harness should comply with applicable safety standards and regulations, such as UL standards, CE certification, etc., to ensure that the wiring harness will not pose a risk to personal safety and equipment safety in the process of using the wiring harness. 2. Compliance with the requirements of electrical performance: the wiring harness should meet the requirements of the electrical performance of the connected equipment, including resistance, current, voltage and other parameters of the Qualified range. 3. Insulation performance requirements: the insulation layer of the harness should have sufficient insulation performance to prevent leakage and short-circuit occurrences. Insulation resistance should meet the specified lower value. 4. durability requirements: the harness should have sufficient durability to maintain stable performance over the service life, resistance to mechanical stress, vibration, humidity and other environmental factors. 5. marking requirements: the harness should be clearly marked, including model, specification, date of production, manufacturer and other information to facilitate traceability and identification. 6. protection requirements: the harness should have a Certain protective properties, such as fire, water, chemical resistance, etc., to adapt to different working environments and application scenarios. Please note that specific wiring harness testing requirements and standards may vary according to different industries, and applications, so when designing and producing wiring harnesses, you need to comply with the applicable standards and specifications to ensure the quality and safety of the wiring harness.
