What Should be Tested in A Wire Harness

Testing is a very important process for a Wire Harness. If no testing, the miswiring will result in shot circuit and damage the device. Then what should be testing in a Cable Kit?

• Connection test ‌
  

 Detect the Cable Assembly for open circuit, short circuit, dislocation and other problems to ensure the integrity of current and signal transmission.

• ‌ Resistance test ‌
  

 A. onductor resistance and contact resistance tests to verify the electrical conductivity and connection stability of the harness.

 B. Measure insulation resistance against the risk of current leakage or short circuit.

• ‌ Withstand pressure test ‌
  

Apply high voltage to verify insulation bearing capacity and avoid breakdown accident.

Physical characteristics test

• ‌ Size detection ‌
  

 Measure harness length, diameter, branch position, etc., to ensure assembly requirements.

• ‌ Mechanical strength test ‌
  

 Includes swing tests, tensile strength tests, vibration/impact tests to assess the durability of the harness under stress or motion.

• ‌ Appearance check ‌
  

Check for physical damage, such as sheath damage, corrosion or loose connectors. ‌

After all things above done,you can ensure a good wire harness to the customers.
