This standard specifies requirements, test methods, inspection rules, marking, Encasement and storage for cold-coated zinc coatings. It applies to organic coatings with high zinc content applied at room temperature, consisting of zinc powder, organic Resin, solvent, etc. It is mainly used for cathode protection on exposed surfaces of steel substrates and repair of damage caused by plating (or spraying) zinc coatings. However, this standard does not apply to multi-component zinc-rich primers. Standard documents cited include determination of non-volatile-matter content of Paints, varnish and plastics, determination of drying time of paint film, determination of flexibility of paint film, determination of impact resistance of paint film, rating method of Paints and varnish coating aging, determination of neutral salt spray performance of Paints and varnish, adhesion test of Paints and varnish pulling method, zinc powder, representation and determination of numerical revision rules and limit values, visual evaluation of surface cleanliness of steel surface preparation before coating, Paints and varnish standard test plates, Temperature Humidity of Coating Specimen Condition Adjustment and Test Paints and varnish film cross-cut test, Coating product Encasement mark, Coating steel surface preparation before spray cleaning of steel surface roughness characteristics Part 1, Paints and varnish film thickness determination and zinc-rich primer.
