T/GDID 1032-2021 Construction-grade rigid polyvinyl chloride (PVC-U) pressure-bearing drainage pipe material
Basic Information
Scope
Scope: This document specifies the terms and definitions, materials, product classification, requirements, test methods, inspection rules, and marking for hard polyvinyl chloride (PVC-U) pressure-bearing drainage pipes for building use (hereinafter referred to as "pipes"). This document is applicable to pipes made of polyvinyl chloride (PVC) resin as the main raw material, which are extruded and used in pressure-bearing drainage systems with a working pressure not exceeding 1.0 MPa in buildings, high-rise buildings' pressure-flow drainage systems, semi-pressurized drainage systems, and gravity-flow drainage systems. When considering the design of drainage pipe systems for ultra-high-rise buildings' pressure-flow drainage systems, semi-pressurized drainage systems, and gravity-flow drainage systems, the hydrostatic test pressure of the pipes used should be greater than twice the hydrostatic pressure generated by the filling of the drainage pipe system with water. Main technical contents: The main technical contents include terms and definitions, materials, product classification, requirements, test methods, inspection rules and marking, transportation, and storage.
