Significance and Use
Measurement of the thickness of a coating is essential to assessing its utility and cost.
The coulometric method destroys the coating over a very small (about 0.1 cm2) test area. Therefore its use is limited to applications where a bare spot at the test area is acceptable or the test piece may be destroyed.
1.1 This test method covers the determination of the thickness of metallic coatings by the coulometric method, also known as the anodic solution or electrochemical stripping method.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
