标准范围

本文件与ISO 11298-1一起，规定了用于供水网络改造的紧密配合衬里系统的要求和试验方法，该供水网络输送人类用水，包括原水取水管道。它适用于制造的管道和配件，以及安装的衬里系统。它适用于实心壁单层或共挤层结构的聚乙烯（PE）管道，在工厂或现场减少，以提供紧密配合的独立或交互式压力管道衬里，以及用于衬里系统施工的相关配件和接头。它不适用于管道外部有可剥离、连续、热塑性附加层的PE涂层管道。适用于在20°C的工作温度下作为参考温度使用的PE管、配件和组件。注:对于在大于20°C且高达40°C的恒定温度下运行的应用，见ISO 4427-1:2007，附录A。

This document, in conjunction with ISO 11298？1, specifies requirements and test methods for close-fit lining systems intended to be used for the renovation of water supply networks, which transport water intended for human consumption, including raw water intake pipelines.It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable to polyethylene (PE) pipes of either solid wall single layer or co-extruded layer construction, which is reduced in the factory or on site to provide a close-fitting independent or interactive pressure pipe liner, as well as associated fittings and joints for the construction of the lining system. It is not applicable to PE coated pipes having a peelable, contiguous, thermoplastic additional layer on the outside of the pipe.It is applicable to PE pipes, fittings and assemblies intended to be used at an operating temperature of 20 °C as the reference temperature.NOTE For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see ISO 4427？1:2007, Annex A.
