Salt spray test is a kind of environment test which mainly used salt spray test equipment to test the product or metal material corrosion resistance.

 It is divided into two major categories, one is the natural environment exposure test, the other is artificial accelerated simulation salt spray environment test. Artificial simulation of salt fog test is the use of a has certain space in the volume of test equipment, salt fog test box, in the volume space with artificial methods, resulting in salt fog environment of the product resistance to salt fog corrosion performance quality assessment. Compared with the natural environment, the salt spray environment of chloride salt concentration can be natural salt spray environment content several times or dozens of times, the corrosion speed greatly improved. 

The salt spray test, obtained the result of time is greatly shortened.
