Pitting corrosion is a type of localized corrosion that occurs when metal surfaces are exposed to corrosive substances. The standard specifies the requirements for testing the resistance of metallic materials to pitting corrosion by neutral salts. The test involves exposing samples to a solution of sodium chloride and measuring the time required for visible pits to form.
The standard requires that samples be prepared according to specific procedures, including cleaning, degreasing, and drying. The test procedure involves placing the sample in a solution of sodium chloride and monitoring the time required for visible pits to form. The results are then evaluated using a set of criteria specified in the standard.
