This test method allows the accurate determination of copper content in formulated paints as a means of verifying composition (see Test Methods D 283).

1.1 This test method is for the analytical determination of copper in liquid samples of antifouling coatings. The procedure outlines in detail equipment, reagents, and necessary steps to satisfactorily determine the concentration of copper in paint. Conversion to specific copper compounds can be made by appropriate gravimetric factors.

1.2 The values stated in SI units are to be regarded as standard. The inch-pound units given in parenthesis are for information only.

1.3 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.
