无压力排水和污水的塑料管道系统 - 基于不饱和聚酯树脂（UP）的玻璃增强热固性塑料（GRP）制成的非圆形管道和接头 - 尺寸 要求和试验

[中文适用范围]： 本文件规定了由玻璃纤维增强热固性塑料（GRP）制成的管道系统及其部件的所需性能，该塑料基于不饱和聚酯树脂（UP），旨在用于包括涵洞在内的无压排水或排污。 采购方或规范制定者有责任根据其特定要求以及任何相关的国家法规和安装实践或规范，做出适当的选择。 本文件适用于具有柔性或刚性接头的非圆形GRP-UP管道，主要用于埋地安装，但也可用于对现有非圆形管道进行内衬修复。 注1：GRP-UP包括带有乙烯基酯内衬或完全由乙烯基酯制成的管道。 注2：符合本文件的管道系统也可用于非埋地应用，前提是在管道、管件和接头的设计中考虑环境（例如紫外线辐射）和支撑的影响。 本文件适用于公称尺寸从DN 150到DN 4000的管道、管件及其接头，这些管道、管件及其接头旨在用于在正常使用条件下输送地表水或污水。 [外文原描述]： This document specifies the required properties of the piping system and its components made from glass-reinforced thermosetting plastics (GRP), based on unsaturated polyester resin (UP) intended to be used for drainage or sewerage without pressure including culverts. It is the responsibility of the purchaser or specifier to make the appropriate selections taking into account their particular requirements and any relevant national regulations and installation practices or codes. This document is applicable to non-circular GRP-UP pipes, with flexible or rigid joints, primarily intended for use in buried installations but may also be used to reline existing non-circular pipe lines. NOTE 1 GRP-UP includes pipes with vinyl ester liners or made entirely from vinyl ester. NOTE 2 Piping systems conforming to this document can be used also for non-buried applications provided the influence of the environment, e.g. from UV-radiation, and the supports are considered in the design of the pipes, fittings and joints. This document is applicable to pipes, fittings and their joints of nominal sizes from DN 150 to DN 4000, which are intended to be used for the conveyance of surface water or sewage at normal service conditions.
