标准范围
本文件规定了由聚乙烯（PE）制成的用于地下或地上应用的管道和/或配件组件的适用性特性，旨在输送人类消费的水、处理前的原水、压力下的排水和污水、真空下水道系统以及用于其他目的的水。注1预期用途包括敷设于水中的排海口及悬挂于桥下的管道。注2本文件仅供产品制造商用于根据ISO 4427 2和/或ISO 4427 3评估组件在正常和极端条件下连接在一起时的性能。它不适用于管道系统的现场测试。本文件还规定了本文件中提及的测试方法的测试参数。与ISO 4427系列的其他部分一起，本文件适用于PE管道、配件、它们的接头以及具有PE和其他材料部件的接头，预期在以下条件下使用:a)最大允许工作压力(PFA)高达并包括25巴[1]；b)20℃的操作温度作为参考温度。注3对于其他工作温度，指南见ISO 4427 1:20 19附录A。ISO 4427系列涵盖了一系列最大允许工作压力，并给出了有关颜色的要求。[1]1巴=0.1 MPa=105巴；1MPa=1N/mm2。
This document specifies the characteristics of the fitness for purpose of pipes and/or fittings assemblies made from polyethylene (PE) for buried or above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drainage and sewerage under pressure, vacuum sewer systems, and water for other purposes.NOTE 1 The intended uses include sea outfalls, laid in water and pipes suspended below bridges.NOTE 2 This document is intended to be only used by the product manufacturer to assess the performance of components according to ISO 4427？2 and/or ISO 4427？3 when joined together under normal and extreme conditions. It is not intended for on-site testing of pipe systems.This document also specifies the test parameters for the test methods referred to in this document.In conjunction with the other parts of the ISO 4427 series, this document is applicable to PE pipes, fittings, their joints and to joints with components of PE and other materials, intended to be used under the following conditions:a) a maximum allowable operating pressure (PFA) up to and including 25 bar[1];b) an operating temperature of 20 °C as the reference temperature.NOTE 3 For other operating temperatures, guidance is given in ISO 4427？1: 2019, Annex A.The ISO 4427 series covers a range of maximum allowable operating pressures and gives requirements concerning colours.[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
