GB/T 39380.2-2022Chlorinated poly (vinyl chloride ) (PVC-C) piping system for fire sprinkler installations—Part 2: Fittings (English PDF)

1 Scope

This document stipulates that the chlorinated polyvinyl chloride (PVC-C) compounding material is used as the raw material, and the chlorinated polyvinyl chloride (CPVC) for sprinkler fire extinguishing is injection molded.

(PVC-C) pipe fittings (hereinafter referred to as "pipe fittings") materials, product classification, requirements, test methods, inspection rules and signs, packaging, transportation and storage.

This document is applicable to the working pressure specified in GB 50084 not greater than 1.2MPa, and the ambient temperature not lower than 4°C and not higher than

70°C pipe fittings are used for automatic sprinkler systems in places where the fire hazard level is light hazard level and medium hazard level I.

This document, together with Part 1 of GB/T 39380, applies to the plastic piping system specified in GB 50084.
