Jetosh company has more than 20 years of rich experience in the wire harness, terminal processing industry .In order to pursuit of goals, high standards of production concept, Jetosh company has formulated an optimization plan on quality, which has been favored and valued by many customers, and wire harness processing test is qualified checkpoint, then the editor of Jetosh explained the test process of the harness processing:


1. Installed to the test function of the machine, you can swing the tail of the connector to see if there are bad faults, etc .;

2. Requirements for common test parameters, the maximum resistance is 2Ω or 1Ω + the wire's own resistance (whichever is greater), and the maximum current is determined by the test equipment

3. The withstand voltage (DWV) test is a DC or AC high voltage test used to verify whether the component can work safely at the rated voltage and withstand the instantaneous spike voltage caused by switching, surge and other similar phenomena, This test can confirm whether the insulation materials and spacing between components are appropriate.

4. Insulation resistance (IR) test (the humidity of the test environment is <80% rh) <> is a high-voltage test used to verify the resistance of insulating materials. When the measured resistance value is lower than specified or the test equipment detects leakage, it indicates failure. For IR tests, the test time can be reduced to the time required for the current to stabilize. If the dielectric withstand voltage test uses DC, the insulation resistance test can be measured simultaneously. If the DWV test and the IR test are performed separately, the IR test should be performed after the DWV test.

Through the above harness processing test process, I hope that it will be helpful to everyone in harness testing. Jetosh is dedicated to the development and production of wire harnesses, terminals and connectors for more than 20 years.
