标准范围
ISO 25780:2011规定了由基于不饱和聚酯树脂(UP)的玻璃增强热固性塑料(GRP)制成的管道系统及其部件的性能，用于有压力或无压力的供水、灌溉、排水或污水处理系统。ISO 25780:2011适用于带有柔性接头的GRP-UP管道系统，旨在使用顶升技术进行安装。它规定了由GRP-UP制成的管道的特性，有或没有骨料或填料，还规定了ISO 25780:2011中提到的测试方法的测试参数。ISO 25780:2011适用于尺寸范围为DN100至DN4000的管道和接头，用于在温度高达50°C的情况下输送水或污水，无论有无压力。ISO 25780:2011涵盖了改进接头设计的要求，并根据管道系统声明的标称压力等级规定了接头的型式试验性能要求m和系统所需的接头挠度能力。
ISO 25780:2011 specifies the properties of the piping system and its components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) for water supply, irrigation, drainage or sewerage systems with or without pressure.ISO 25780:2011 is applicable to GRP-UP piping systems, with flexible joints, intended to be installed using jacking techniques. It specifies the characteristics of pipes made from GRP-UP, with or without aggregates or fillers and also specifies the test parameters for the test methods referred to in ISO 25780:2011.ISO 25780:2011 is applicable to pipes and joints with a size range from DN100 to DN4000 which are intended to be used for the conveyance of water or sewage at temperatures up to 50oC, with or without pressure.ISO 25780:2011 covers requirements to improve the design of the joint and specifies type test performance requirements for the joints as a function of the declared nominal pressure rating of the pipeline system and the required joint deflection capability of the system.
