Test preparation:

1. Prepare the product: Prepare 4 cables and make conduction test to confirm them with good conduction for the samples to be tested.

2. The sample should be placed under normal test atmospheric conditions until temperature is stable.

Salt Spray Test operation steps :

1. The 4 samples cable normal exposure placed on the shelves in the test chamber, the samples to maintain a certain distance between them to avoid the corrosive substances affect each other.

2. Inject sufficient 5% concentration of saline and close the cover.

3. Set the temperature as 35℃ and total test time as 24H.

4. Press the start button to start the test.

5. Take out the samples and clean them.

6. Check the samples for appearance and electrical performance.

Test Result Determination :

1. No mechanical separation, the appearance should not be damaged.

2. No corrosion or deformation on metal part and no damage on plastic part.

3. The metal part of the sample shall not appear oxidation or rust.

4. The cable should be with good conductivity after the test, and can transmit data normally.
