This test method covers procedures for determining the mass [weight] of coating on aluminum-coated iron or steel sheets and wire, and on other aluminum-coated iron and steel articles. The final results determined by this test method shall be expressed in SI or inch-pound units, depending on the units used in the material specification to which the results are to be compared. Certain portions of the procedure involving determination of specimen mass [weight] traditionally have been performed in SI units, and corresponding inch-pound units are not included. For sheet products, the final results are expressed as either coating mass [weight] total both sides, or coating mass [weight] separately on each side, depending on the specified requirements.
