标准范围

本文件与ISO 11299-1一起，规定了用于燃气供应网络改造的紧密配合衬里系统的要求和试验方法。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，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衬，以及用于衬里系统施工的相关配件和接头。本文件不适用于在管道外部具有可剥离、连续、热塑性附加层的涂层PE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:对于其他工作温度，ISO 4437-5:2014给出了指南。

This document, in conjunction with ISO 11299？1, specifies requirements and test methods for close-fit lining systems intended to be used for the renovation of gas supply networks.It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable to polyethylene (PE) pipe 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. This document is not applicable for coated PE pipes having a peelable, contiguous, thermoplastics additional layer on the outside of the pipes.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 other operating temperatures, guidance is given in ISO 4437？5:2014.
