Over deze norm
This International Standard specifies the properties of piping system components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) for drainage or sewerage with or without pressure, as well as the properties of the system itself. This International Standard is applicable to GRP-UP piping systems, with flexible or rigid joints with or without end thrust load-bearing capability, primarily intended for use in buried installations. This International Standard is applicable to pipes, fittings and their joints of nominal sizes from DN 50 to DN 4000 which are intended to be used for the conveyance of drainage or sewerage at temperatures up to 50 °C, with or without pressure. In a pipework system, pipes and fittings of different nominal pressure and stiffness ratings may be used together. Clause 4 specifies the general aspects of GRP-UP piping systems 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 may have a thermoplastics or thermosetting resin liner. Clause 5 also specifies the test parameters for the test methods referred to in this International Standard. Clause 6 specifies the characteristics of fittings made from GRP-UP, with or without a thermoplastics or thermosetting resin liner, intended to be used in the field of drainage or sewerage. Clause 6 specifies the dimensional and performance requirements for bends, branches, reducers, saddles and flanged adaptors. Clause 6 is applicable to fittings made using any of the following techniques: a) fabrication from straight pipes; b) moulding by 1) filament winding, 2) tape winding, 3) contact moulding, 4) hot or cold compression moulding.Clause 7 is applicable to the joints to be used in GRP-UP piping systems to be used for the conveyance of surface water or sewerage, both buried and non-buried. It covers requirements to prove the design of the joint. Clause 7 specifies type test performance requirements for the following joints as a function of the declared nominal pressure rating of the pipeline or system: c) socket-and-spigot or mechanical joints; d) locked socket-and-spigot joints; e) cemented or wrapped joints; f) bolted flange joints.
