标准范围

本文件规定了由定向未增塑聚氯乙烯（PVC-O）制成的实壁管道的一般特性，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。与ISO 16422-2、ISO/TS 16422-3、ISO 16422-5和ISO 1452-4一起，本文件适用于PVC-O管道和PVC-O配件，以及阀门、其接头和与其他塑料和非塑料材料部件的接头，这些部件旨在用于以下用途: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），用于人类消费和一般用途以及压力下的废水。本文件也适用于输送45？°C。温度在25度之间？°C和45？°C，参见ISO 16422-2:20 23，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 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.
