YYE-007 PVC Anti Corrosion Salt Spray Test Equipment, Environmental Testing Chamber This machine provides a standardized test method to evaluate the corrosion resistance of coated samples. The salt spray test is an accelerated corrosion test that produces corrosive attack on coated samples to predict their suitability as protective finishes. The appearance of corrosion products (oxides) is evaluated after a specific period. Test duration depends on the coating's corrosion
