The difference between salt spray machine and natural environment exposure test：

Salt spray test is a kind of environmental test which mainly uses artificial simulated salt spray environmental conditions created by salt spray test equipment to check the corrosion resistance of products or metal materials. It is divided into two categories, one is natural environmental exposure test, the other is artificial accelerated simulated salt spray environmental test. Artificial simulation of salt spray environment test is to use a test equipment with a certain volume space - salt spray test chamber, in its volume space with artificial methods to create salt spray environment to evaluate the corrosion resistance of the product.

Compared with the natural environment, the salt concentration of chloride in the salt spray environment can be several times or dozens of times of the salt spray content in the general natural environment. For example, it may take 1 year for a product sample to be corroded under natural exposure, while similar results can be obtained in 24 hours under artificial simulated salt spray environment.
