The salt spray test is an environmental test that mainly uses artificially simulated salt spray environmental conditions created by the salt spray test chamber 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 artificial accelerated simulated salt spray environment test.

Salt spray test chamber and salt spray test and the relationship with the actual

The artificial simulated salt spray environment test is to use a kind of test equipment with a certain volume of space-the salt spray test box, using a manual method in its volume space to create a salt spray environment to evaluate the product's salt spray corrosion resistance . Compared with the natural environment, the salt concentration of the chloride in the salt spray environment can be several times or tens of times of the general natural environment salt spray content, which greatly improves the corrosion rate. The time is also greatly reduced. For example, if a product sample is tested in a naturally exposed environment, it may take one year to corrode. However, if the test is performed under artificially simulated salt spray conditions, as long as 24 hours, similar results can be obtained.
