With the development of technology and new energy, there are more and more application scenarios for cable harnesses. In addition to material selection and processing of wire harnesses in accordance with waterproof application specifications, necessary processing should be done on the waterproof performance of wire harnesses and cables to improve the performance and quality of wire harnesses and cables.

Today we are sharing about the air tightness testing process of wire harnesses.

The customer has high waterproof requirements for this wiring harness product, requiring the test pressure to reach 100Kpa and the upper limit of leakage not to exceed 50pa.

Equipment used: Hirays HC classic series air tightness detector

Testing method: Direct testing method is adopted, and fixtures and tooling are customized according to the structure of the wire harness.Select the set program and start testing.

Program parameters: intake pressure 100Kpa, intake time 3s, pressure stabilization 5s, test time 5s, deflation time 2s.If the leakage value does not exceed 50pa, it means that the air tightness test of the wiring harness has passed, and the test result will also show OK.
