标准摘要
[中文适用范围]： 本文件与 ISO 11297-1 和 ISO 11296-4 一起规定了用于翻新液压和气动加压地下排水和污水网络的现场固化管道和配件的要求和测试方法，工作温度高达 50 °C。 它适用于 ISO 11295 中定义的独立（全结构，A 级）和交互（半结构，B 级）压力管道衬里，不依赖于现有管道的粘附。 它适用于各种热固性树脂系统与相容的纤维载体材料、增强材料和其他与工艺相关的塑料组件的结合使用（见 5.1）。 它不包括耐磨性、循环载荷或冲击性的要求或测试方法，这些要求或测试方法超出了本文件的范围。 [外文原描述]： ISO 11297-4:2018, in conjunction with ISO 11297‑1 and ISO 11296‑4, specifies requirements and test methods for cured-in-place pipes and fittings used for the renovation of hydraulically and pneumatically pressurized underground drainage and sewerage networks with service temperatures up to 50 °C. ISO 11297-4:2018 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. ISO 11297-4:2018 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). ISO 11297-4:2018 does not include requirements or test methods for resistance to abrasion, cyclic loading or impact, which are outside the scope of this document.
