scope:

1.1 This method describes the conditions and equipment for measuring the impedance of anodic coatings on aluminum. Such measurements have been used to evaluate the quality of seal of an anodic coating. The method does not prescribe the procedure for producing the anodic coating, nor the postanodizing treatment usually described as "sealing."

1.2 This method is applicable to the rapid, nondestructive testing of anodic coatings. The interpretation of results and correlation of data with service experience and other tests are not within the scope of this method.
