Foreword

GB/T 39380 "Chlorinated Polyvinyl Chloride (PVC-C) Piping System for Water Sprinklers" is divided into 2 parts.

---Part 1: Pipes;

---Part 2: Pipe fittings. This part is Part 1 of GB/T 39380.

This section was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This part of GB/T 39380 specifies the use of chlorinated polyvinyl chloride (PVC-C) mixtures as raw materials and extruded water sprinklers.

Terms and definitions, symbols and abbreviations, materials, requirements, test methods, inspections of chlorinated polyvinyl chloride (PVC-C) pipes (hereinafter referred to as "pipes") Inspection rules and signs, packaging, transportation and storage.

This part is applicable to the working pressure of 1.2MPa specified in GB 50084-2017, and the ambient temperature for use is not lower than 4°C and not higher than 70°C pipes are used for automatic sprinkler systems in places where the fire hazard level is light hazard level and medium hazard level I.

This part and other parts of GB/T 39380 are applicable to the plastic piping system of GB 50084-2017.
