What is the salt spray resistance test?

       Salt spray test is an environmental test that mainly uses artificial simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is natural environmental exposure test, and the other is artificial accelerated simulated salt spray environmental test. The artificial simulated salt spray environment test is to use a kind of test equipment with a certain volume space - the salt spray test box, in its volume space, use artificial methods to create a salt spray environment to assess the product's salt spray corrosion resistance performance and quality . Compared with the natural environment, the salt concentration of chloride in the salt spray environment can be several times or tens of times that of the general natural environment salt spray, which greatly increases the corrosion rate. The salt spray test is carried out on the product to obtain the result. time is also greatly shortened. For example, if a product sample is tested in a natural exposure environment, it may take 1 year to wait for it to corrode, while in the artificial simulated salt spray environment, it only takes 24 hours to obtain similar results.
