Salt spray test is an environmental test that uses salt spray testing equipment to assess the corrosion resistance of products or metal materials. It can be divided into two categories, one is natural environment exposure test, and the other is artificial accelerated simulated salt spray environment test. The artificial simulation of salt spray environment test uses a salt spray test chamber and artificial methods to create a salt spray environment within its volumetric space to assess the quality of the product's salt spray corrosion resistance performance. The salt concentration of chlorides in salt spray environments is several times or tens of times higher than that in natural environments, greatly increasing the corrosion rate. Below we will introduce relevant knowledge to everyone View >>
