Salt spray test is an environmental test that mainly uses artificially simulated salt spray environmental conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials. It is divided into two categories, one is the natural environment exposure test, and the other is the artificially accelerated simulated salt spray environment test.
Artificially simulated salt spray environment test is the use of a certain volume of space test equipment - salt spray test chamber, in its volume of space with artificial methods, resulting in salt spray environment to the quality of salt spray corrosion resistance of products to assess.
It is compared with the natural environment, the salt concentration of chloride in its salt spray environment, can be several times or dozens of times the salt spray content of the general natural environment, so that the corrosion rate is greatly increased, the salt spray test on the product, the time to produce results is also greatly shortened.
Such as in the natural exposure to the environment of a product sample test, to be its corrosion may take 1 year, while in the artificial simulation of salt spray environmental conditions test, as long as 24 hours, you can get similar results.
Artificially simulated salt spray tests also include neutral salt spray tests, acetate spray tests, copper salt accelerated acetate spray tests and alternating salt spray tests.
