Scope: This standard specifies a test method for the resistance of metals to corrosion in the presence of chloride ions, primarily sodium chloride derived from marine and road deicing salts. This standard specifies equipment and test procedures for accelerated corrosion testing that simulates atmospheric corrosion conditions in a highly controlled manner. Metals in this standard include metal materials with corrosion protection and without corrosion protection. This laboratory accelerated corrosion test is applicable to: - metals and their alloys; - metallic coatings (anodic and cathodic); - chemical conversion coatings; - organic coatings on metals. It is especially suitable for comparative experiments on the optimization of surface treatment methods.
