标准摘要
[中文适用范围]： 本文件规定了由取向未增塑聚氯乙烯（PVC-O）制成的实壁管的一般特性，该管用于地下或地上（避免阳光直射）的管道系统，用于供水、埋地排水、污水处理、处理过的废水和加压灌溉。与 ISO 16422-2、ISO/TS 16422-3、ISO 16422-5 和 ISO 1452-4 结合，本文件适用于 PVC-O 管和 PVC-O 管件，以及阀门、其接头和与其他塑料和非塑料材料部件的接头，旨在用于以下用途：a) 水管和服务管线；b) 建筑物内外输水；c) 加压排水、污水处理和处理过的废水；d) 加压灌溉。本文件适用于用于供应温度不超过 25°C 的压力水（冷水）的管道系统，供人类消费和一般用途以及加压废水。本文件还适用于用于输送温度不超过 45°C 的水和废水的组件。对于 25°C 至 45°C 之间的温度，请参见 ISO 16422-2:2023，图 C.1。根据本文件，管道系统用于输送压力不超过 25 bar1) 的冷水，尤其适用于需要特殊性能要求的应用，例如冲击载荷和压力波动，压力不超过 25 bar。 [外文原描述]： This document specifies the general characteristics of solid-wall pipes made of oriented unplasticized poly(vinyl chloride) (PVC-O) for piping systems intended to be used underground or above-ground (where protected from direct sunlight), for water supply, buried drainage, sewerage, treated waste water and irrigation under pressure . In conjunction with ISO 16422-2, ISO/TS 16422-3, ISO 16422-5 and ISO 1452-4, this document is applicable to PVC-O pipes and PVC-O fittings, as well as to valves, their joints and to joints with components of other plastics and non-plastics materials intended to be used for the following: a) water mains and services lines; b) conveyance of water for both outside and inside buildings; c) drainage, sewerage and treated wastewater under pressure; d) irrigation under pressure. This document is applicable to piping systems intended for the supply of water under pressure up to and including 25 °C (cold water), intended for human consumption and for general purposes as well as for wastewater under pressure. This document is also applicable to components for the conveyance of water and wastewater up to and including 45 °C. For temperatures between 25 °C and 45 °C, see ISO 16422-2:2023, Figure C.1. The piping system according to this document is intended for the conveyance of cold water up to pressures of 25 bar [1] and especially in those applications where special performance requirements are needed, such as impact loads and pressure fluctuations, up to pressure of 25 bar. [1] 1 bar = 0,1 MPa = 10 5 Pa; 1 MPa = 1 N/mm 2
