    Abstract

    This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. The thickest coating classes are usually referred to as "mechanically galvanized". All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster. Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement. All tests results should comply with the given requirements.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers the requirements for a coating of zinc mechanically deposited on iron and steel basis metals. The coating is provided in several thicknesses up to and including 107 μm. The seven thickest classes are usually referred to as mechanically galvanized.

    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.

    Note 1—The performance of this coating complies with the requirements of Specification A153/A153M and MIL-C-81562.

    1.3 The values stated in SI units are to be regarded as the standard. The inch-pound equivalents of SI units are given for informational purposes.
