Salt Spray and Salt Fog Testing

The salt spray test is a standardized test method used to check corrosion resistance of coated samples. Coatings provide corrosion resistance to metallic parts. Since coatings can provide a high corrosion resistance through the intended life of the part in use, it is necessary to check corrosion resistance by other means. Salt spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion.

Cyclic Corrosion

Cyclic corrosion testing is a more realistic way to perform salt spray tests.Actual environmental conditions usually include both wet and dry conditions, thus it makes sense to pattern accelerated laboratory tests after these natural cyclic conditions.

Acetic Seawater (SWAAT)and Copper Acetic Test (CASS)

The SWAAT test can be used to determine time to perforation primarily on aluminum alloy used to manufacture heat exchangers, and on plated parts. The CASS test is an accelerated corrosion test using copper chloride for some electrodeposits for anodic coatings on aluminum.
