Describes a method of evaluating the condition of coated test specimens that have been exposed to corrosive environments for test purposes. Special precautions must be taken when rating similar panels exposed to acceleration corrosion tests. Any modifications needed to adapt the method to rating acutal production parts are not considered. Applicable only to protective coatings that are anodic to the substrate. Covers normative references, definitions, principle, method of inspection, assignment of appearance rating, assignment of corrosion rating, evaluation of results in the form of corrosion grades and test report.
