Scope

Scope: This document specifies the terms and definitions, classification, requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of anti-corrosion coatings for steel structures. This document applies to anti-corrosion coatings for steel structures used in African environments. Main technical content: 1. Classification: This standard applies to anti-corrosion coatings for steel structures used to protect metal surfaces. The standard classifies steel anti-corrosion coatings into three categories: primer, intermediate coat, and topcoat. Primers can be divided into inorganic zinc-rich primers, epoxy zinc-rich primers, epoxy phosphoric acid zinc primers, and epoxy sealing primers according to their usage requirements. Intermediate coats can be divided into epoxy (thick-film) coatings, epoxy (zinc-rich) coatings, and epoxy glass flake coatings. Topcoats can be divided into acrylic aliphatic polyurethane topcoats, fluorocarbon topcoats, and silicone topcoats. 2. Preparation of test samples: Unless otherwise specified, Table 4 of the "Steel Structure Anti-Corrosion Coatings" specifies the types of substrates, substrate sizes, and dry film thickness of the coating required for testing. The application method can be brush application, roll application, or spray application, among which spray application can achieve a more uniform and smooth coating effect than brush application and roll application. Manufacturers are allowed to negotiate customized board requirements with the testing party, but any deviations from the standard must be noted in the testing report. 3. Technical requirements: The technical requirements (Tables 1-3
