Historical Standard: ASTM D7396-07 Standard Guide for Preparation of New, Continuous Zinc-Coated (Galvanized) Steel Surfaces for Painting
SUPERSEDED (see Active link, below)
ASTM D7396
1. Scope
1.1 This guide covers surface cleaning and eight methods of treating new zinc-coated by the continuous process (galvanized) surfaces produced by either the hot-dip method or by electroplating. This guide covers surfaces that have not been treated previously at the mill to provide temporary protection against staining by moisture other than by easily removed protective oils (see Appendix X1). For preparing surfaces of new or weathered items of zinc-coated steel produced by batch processing, refer to Practice D 6386 .
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
