The composite temperature, humidity and salt spray test is the closest to the actual natural conditions in the accelerated corrosion test. Fog, dry, humidity, standing at room temperature, low temperature and other environments are combined, and the program can be written arbitrarily or tested separately.
The main test items are for products used under severe environmental changes, such as automobile and motorcycle parts, aviation equipment, photographic equipment, building materials, electro-coating coatings, and electronic and electrical systems, etc. Metals are suitable for electrochemical corrosion resistance.
