Salt mist test is a standardized test method to check corrosion resistance of coatings and entire products. Corrosion not only affects metals, but also high alloyed, tempered materials, plastics and painted surfaces. The test duration depends on the environmental conditions of the product in real life. High humidity, salty air, sea water and gritting salt influence corrosiveness of the product. Salt mist / salt spray testing is popular because it is quick and standardized. To accelerate the corrosion, it is possible to introduce scratches in a coating. The length of the dendrites formed during the corrosion test is a coating measure. Salt mist testing is often for quality control of materials and less for pretending the life time of product in the real world.

A salt fog test is an evaluate methodology that leverages salt water a corrosion accelerant to determine how quickly rust develops on the testing subject conducted within the confines of a salt spray chamber. Salt fog testing uses pressurized air to saturate metals coatings, stone or other materials that have the potential to rust, which produces the corrosive environment that leads to oxidation. Oxidation is the chemical process that occurs when oxygen and other substances collide with one another. In this case, those other substances are sodium and chloride the constituent elements of salt.
