Basic Information
Scope
Scope: This document specifies the term definitions, symbols and abbreviations, material requirements, technical requirements, test methods, inspection rules, marking, transportation and storage for hard polyvinyl chloride (PVC-U) core foamed spiral pipes (hereinafter referred to as pipes) used in building drainage, which are mainly made of polyvinyl chloride resin as the main raw material and added with necessary additives, and then formed by compound co-extrusion. This document is applicable to drainage riser pipes in industrial and civil buildings with a continuous discharge temperature not exceeding 40℃ and an instantaneous discharge temperature not exceeding 80℃. Main technical contents: - Requirements for longitudinal shrinkage rate (%) of pipe physical and mechanical properties: ≤9%, without cracking or peeling; - Requirements for apparent density (g/cm3): 0.90~1.20; - Requirements for flatness test: no cracking or peeling; - Requirements for hammer impact test TIR (0℃): ≤10%; - Requirements for lead content (mg/kg): ≤200mg/kg.
