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就地固化管道和配件的要求和试验方法，这些管道和配件输送人类用水，包括原水取水管道。它适用于ISO 11295中定义的独立（完全结构，A类）和交互式（半结构，B类）压力管道内衬，其不依赖于现有管道的附着力。它适用于各种热固性树脂系统的使用，以及兼容的纤维载体材料、增强材料和其他与工艺相关的塑料组件（见5.1）。它不包括通过弯管的CIPP衬里的抗循环载荷或额定压力的要求或试验方法，这些要求或试验方法不在本文件的范围内。它适用于在高达25°C的工作温度下使用的就地固化管道衬里系统。注？对于在高于25°C的工作温度下运行的应用，系统供应商可提供关于重新评级系数的指南。

This document, in conjunction with ISO 11298？1, specifies requirements and test methods for cured-in-place pipes and fittings used for the renovation of water supply networks, which transport water intended for human consumption, including raw water intake pipelines.It applies to independent (fully structural, class A) and interactive (semi structural, class B) pressure pipe liners, as defined in ISO 11295, which do not rely on adhesion to the existing pipeline. It applies to the use of various thermosetting resin systems, in combination with compatible fibrous carrier materials, reinforcement, and other process-related plastics components (see 5.1).It does not include requirements or test methods for resistance to cyclic loading or the pressure rating of CIPP liners where passing through bends, which are outside the scope of this document.It is applicable to cured-in-place pipe lining systems intended to be used at a service temperature of up to 25 °C.NOTE   For applications operating at service temperatures greater than 25 °C, guidance on re-rating factors can be supplied by the system supplier.
