This document specifies methods of checking the adhesion of electrodeposited and chemically deposited coatings. It is limited to tests of a qualitative nature. This document does not describe certain tests that have been developed at various times to give a quantitative measure of adhesion of metallic coating to a substrate@ since such tests require special apparatus and considerable skill in their performance which renders them unsuitable as quality control tests for production parts. Some of these quantitative tests can@ however@ be useful in research and development work.
