Salt spray testing is employed to assess the corrosion resistance of coatings and materials utilized in the production of items like fasteners. It creates an accelerated corrosive environment to forecast the efficacy of the coating in safeguarding the metal. system for determining weathering characteristics of materials and coatings. Weathering testing is used to improve product durability and is also a tool for decision making. Such tests can be used to predict durability or to monitor changes in mechanical properties during weathering of materials
