Describes 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, including culverts, with or without pressure.

This European Standard 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, including culverts, with or without pressure. In a pipework system, pipes and fittings of different nominal pressure and stiffness ratings may be used together. 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 European Standard is applicable to GRP-UP, with flexible or rigid joints (see 3.33 and 3.34), primarily intended for use in buried installations. NOTE Piping systems conforming to this European Standard can be used also for non-buried applications provided that the influence of the environment, e.g. from UV-radiation, and the supports are considered in the design of the pipes, fittings and joints. It is applicable to pipes, fittings and their joints of nominal sizes from DN 100 to DN 4000, which are intended to be used for the conveyance of surface water or sewage at temperatures up to 50 °C, with or without pressure. This European Standard covers a range of nominal sizes, nominal stiffnesses and nominal pressures. Clause 6 is applicable to fittings made using any of the following techniques: fabricated from straight pipe; moulded by: filament winding; tape winding; contact moulding; hot or cold press moulding. This European Standard is applicable to the joints to be used in GRP-UP piping systems to be used for the conveyance of water, both buried and non-buried. It is applicable to joints, which are or are not intended to be resistant to axial loading. It covers requirements to prove the design of the joint. It specifies type test performance requirements for the following joints as a function of the declared nominal pressure rating of the pipeline or system: socket-and-spigot (either integral with pipe or sleeve coupling) or mechanical joint; locked socket-and-spigot joint; cemented or wrapped joint; bolted flange joint. Recommended practices for the installation of buried pipes made in accordance with this standard is addressed in CEN/TS 14578. Guidelines for the structural analysis of buried GRP-UP pipelines are addressed in CEN/TS 14807. Guidance for the Assessment of Conformity of products made in accordance with this standard is addressed in CEN/TS 14632.
