Is it necessary to do salt spray test for all connector plug-ins?

Salt spray test is an environmental test created by using salt spray experimental equipment to simulate salt spray environmental conditions to assess the corrosion resistance of products or metal materials. Generally, the test is carried out in a salt spray test box with a 5% salt solution, and the exposure time is 48-96 hours. Salt spray is very corrosive to many materials, and has been proven to cause the failure of many connector coating systems, including precious and non-precious metal coatings. Therefore, neither the connector plug-in nor the wiring harness can bypass the salt spray test.

In fact, there are not many equipment that will face the test of salt spray for a long time, most of which are military equipment or equipment in the marine environment. So why does salt spray testing become a project with extensive testing needs? This is considering that when a car or truck is walking, the connector of the chassis may come into contact with the sewage splashing on the tires, especially in the northern winter when it snows, salt will be used to accelerate the melting of the snow on the road. Increase the corrosive power of sewage. This makes the demand for salt spray resistance suddenly increased. These connectors must pass the salt spray test to verify their safety.
