The durability test of the wiring harness is the key to ensuring its long-term stable operation under various harsh conditions. The following are several common durability testing methods:

1. Static thermal aging test

Test objective: To simulate the long-term use of wiring harnesses in high-temperature environments

.

Test method: Place the wiring harness in a constant high temperature environment, usually at the maximum working temperature of the product plus 10, for 72 hours

.

Test results: After the test, it is necessary to check the appearance, insulation resistance, and voltage resistance of the wiring harness to ensure that there are no abnormalities

.

2. Dynamic thermal cycling test

Test objective: To evaluate the performance of the wiring harness in rapidly changing temperature environments

.

Test method: Cycle the wiring harness between high and low temperatures, such as -40 to+125 cycles

.

Test result: Check the functional performance of the wiring harness after temperature changes to ensure no damage

.

3. Low temperature exposure durability test

Test objective: To simulate the long-term use of wiring harnesses in low-temperature environments

.

Test method: Place the wiring harness in a low-temperature environment of -40 ° C for 72 hours

.

Test results: After the test, it is necessary to check the appearance, insulation resistance, and voltage resistance of the wiring harness to ensure that there are no abnormalities

.

4. High temperature exposure durability test

Test objective: To simulate the long-term use of wiring harnesses in high-temperature environments

.

Test method: Place the wiring harness in a high temperature environment with a maximum working temperature of 10 degrees Celsius for 72 hours

.

Test results: After the test, it is necessary to check the appearance, insulation resistance, and voltage resistance of the wiring harness to ensure that there are no abnormalities

.

5. Bending durability test

Test objective: To evaluate the durability of wiring harnesses under frequent bending

.

Test method: Use a motor or cylinder to drive the fixture, perform a specified angle bending test on the wire harness, and complete the specified number of bends

.

Test result: Check for any damage on the outer surface of the wiring harness and conduct a functional test

.

6. Vibration durability test

Test objective: To evaluate the durability of wiring harnesses in vibration environments

.

Testing method: Install the wiring harness on a vibration table and simulate the actual vibration environment during use

.

Test result: Check the appearance and function of the wiring harness to ensure that there is no damage

.

7. Chemical resistance test

Test objective: To evaluate the durability of wiring harnesses in chemical environments
