标准摘要
[中文适用范围]： 本文件规定了用于以下接头的热塑性弹性体 (TPE) 模制密封件所用材料的要求： a) 建筑物内非压力水排放（高达 95 °C 的间歇流）的热塑性管道系统; b) 用于非压力地下排水和污水处理的热塑性管道系统（最高 45°C 的连续流动和最高 95°C 的间歇流动）； c) 热塑性雨水管道系统。 还给出了成品接头密封件的一般要求；考虑到管接头的性能是密封材料特性、密封几何形状和管接头设计的函数，特定应用的任何附加要求均在相关产品标准中规定。 [外文原描述]： This document specifies requirements for materials used for moulded seals made of thermoplastic elastomers (TPEs) for joints in: a) thermoplastic piping systems for non-pressure wastewater discharge (intermittent flow at up to 95 °C) inside buildings; b) thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow at up to 45 °C and intermittent flow at up to 95 °C); c) thermoplastic rainwater piping systems. General requirements for finished joint seals are also given; any additional requirements for a particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design.
