用于压力水输送的定向未增塑聚氯乙烯 (PVC-O) 制成的管道和接头

[中文适用范围]： 本文件规定了用于地下或地上（避免阳光直射）管道系统的定向未增塑聚氯乙烯（PVC-O）实壁管的特性，用于供水、埋地排水、污水处理、处理过的废水和加压灌溉。它还规定了本文件中引用的试验方法的试验参数。与 ISO 16422-1 和 ISO 16422-5 结合，本文件适用于定向 PVC-O 管，无论是否带整体插座，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最高 25°C（冷水）的压力水的管道系统，供人类消费和一般用途以及加压废水。本文件还适用于温度不超过 45 °C 的水和废水输送组件。对于 25 °C 至 45 °C 之间的温度，请参见图 C.1。根据本文件，管道系统旨在输送压力不超过 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 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 wastewater and irrigation under pressure. It also specifies the test parameters for the test methods referred to in this document. In conjunction with ISO 16422-1 and ISO 16422-5, this document is applicable to oriented PVC-O pipes, with or without integral socket, 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 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
