标准范围

本文件规定了由定向未增塑聚氯乙烯（PVC-O）制成的实壁管道的特性，用于地下或地上（防止阳光直射）、供水、地下排水、污水处理、处理废水和压力灌溉的管道系统。它还规定了本文档中提到的测试方法的测试参数。结合ISO 16422-1和ISO 16422-5，本文件适用于定向PVC-O管道，带或不带整体承插，预期用于以下用途:A）？水管和服务管线；b）？建筑物外部和内部的水输送；c）？压力下的排水、排污和处理废水；d）？压力灌溉。本文件适用于在25？°C（冷水），供人类消费和一般用途以及以下的废水压力。本文件也适用于输送45？°C。温度在25度之间？°C和45？℃，见图？C.1.根据本文件的管道系统用于输送压力高达25？巴[1]，特别是在那些需要特殊性能要求的应用中，如冲击载荷和压力波动，压力高达25？酒吧。[1]？1？酒吧=0,1？MPa=105帕；1？MPa=1？N/mm2

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.
