Introduction

Standard Name: Standard Method of Test for Mass [Weight] of Coating on Iron and Steel Articles with Zinc or Zinc-Alloy Coatings

Standard Number: AASHTO T 65M/T 65-23, ASTM A90/A90M-21

Scope:

1.1 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 coatings shall be interpreted to also include zinc-alloy coatings except where specifically stated otherwise.

1.2 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 expressed in inch-pound units.
