ISO 11297-4:2018与ISO 11297-1和ISO 11296-4一起，规定了用于维修工作温度高达50°C的液压和气压地下排水和污水管网的就地固化管道和配件的要求和试验方法。 ISO 11297-4:2018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。 ISO 11297-4:2018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）。 ISO 11297-4:2018不包括本文件范围之外的耐磨性、循环载荷或冲击的要求或试验方法。

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.
