Language in which you want to receive the document.


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 with or without pressure. In a pipework system, pipes and fittings of different nominal pressure and stiffness ratings may be used together.
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, 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 3.37 and 3.38), primarily intended for use in buried installations.
NOTE 2 Piping systems conforming to this European Standard 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.
It is applicable to pipes, fittings and their joints of nominal sizes from DN 100 to DN 3000, 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 4 specifies the general aspects of GRP-UP piping system intended to be used in the field of drainage or sewerage, with or without pressure.
Clause 5 specifies the characteristics of pipes made from GRP-UP with or without aggregates and/or fillers. The pipes can have a thermosetting or thermoplastics liner. Clause 5 also specifies the test parameters for the test methods referred to in this European Standard.
Clause 6 specifies the characteristics of fittings made from GRP-UP with either a thermosetting or thermoplastics liner intended to be used in the field of drainage or sewerage.
