​Specifies the requirements for factory-applied thermal-bonded polymeric corrosion protective coatings (barrier coatings).

This Standard specifies the requirements for factory-applied thermal-bonded polymeric corrosion protective coatings (barrier coatings). For the purposes of this Standard, the term polymeric coating is intended to encompass both thermoplastic and thermosetting coating materials, which are used to coat both the internal and external surfaces of valves and fittings. This Standard covers the following service application areas: (a) Factory-applied coatings and associated coatings used for repair. (b) Ductile iron, grey cast iron, malleable iron, steel and copper alloy based substrates. (c) Valves, fittings and their components and associated equipment.(d) Contact with water, and wastewater up to 50°C.(e) Above and below ground exposure. NOTES: 1 Some coatings may not be suitable for all wastewaters. Compatibility should be checked with the manufacturer. 2 Guidelines on requirements to be specified by the purchaser are given in Appendix A. Means of demonstrating compliance with this Standard are given in Appendix B.
