This test method covers procedures for determining the mass [weight] of coating on iron or steel sheet, wire, and other articles in which the coating is zinc or a zinc alloy, such as zinc-5 percent aluminum (including zinc-5 percent aluminum-mischmetal and zinc-5 percent aluminum-0.1 percent magnesium) or 55 percent aluminum-zinc. In the body of this test method, reference to zinc coating shall be interpreted to also include zinc-alloy coating except where specifically stated otherwise.
The final results determined by this test method shall be expressed in SI units 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.
Current regulation codes and hazard classifications for chemicals used in this test method are listed in 29 CFR 1910.1200.
