    1. Scope

    1.1 This specification covers material and process requirements for electrodeposited zinc coatings applied to iron or steel articles to protect them from corrosion.

    1.2 The coatings are provided in four standard thickness classes (4.1), in the as-plated condition or with one of five types of supplementary finishes (4.2).

    1.3 High strength metals, unless otherwise specified, including high strength steels having a tensile strength greater than 1700 MPa (247 ksi, 46HRC) shall not be electroplated.

    1.4 It does not cover continuous processes for electrodeposited zinc coated steel wire or sheets (see Specification A591/A591M for sheets.)

    1.5 It may be used for fasteners but specific specifications have been developed for manufacturing fasteners in Committee F16 which may be more applicable (see Specifications F1941 and F1941M.

    1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.7 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.

    1.8 This standard has been revised to address RoHS requirements that seek to limit the exposure of workers and the public from exposure to toxic metals. Additional types V and VI have been added to permit non-chromate passivate treatments to be used in replacement of hexavalent chromium.
