ASTM D7396-14

1.1 This guide covers surface cleaning and various methods for treating new, continuous zinc-coated (galvanized) steel surfaces produced by either the hot-dip method or by electroplating. This guide is applicable to only surface preparation for application of liquid paint and coating products, and not for powder coating applications. 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 D6386.
