Significance and Use

The procedures described in this practice are designed to provide uniform zinc coated steel panels for testing of paint, varnish, lacquer, conversion coatings and related products.

The proper description of the zinc coating on the substrate is an important part of this practice. Seemingly slight differences in zinc coating can produce substantial differences in coating performance.

1. Scope

1.1 This practice covers the preparation of zinc-coated and zinc-alloy-coated sheet steel panels to be used for testing paint, varnish, lacquer, conversion coatings, and related products. It covers sheet steel coated with hot dipped galvanized, one-side galvanized, electrogalvanized, zinc-iron alloy coatings (such as galvanneal), and zinc-5 % aluminum alloy coatings. It does not cover steel panels coated with 55 % aluminum-45 % zinc alloy, because these behave more like aluminum than zinc.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This standard does not purport to address all of the safety problems, 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.
