Plastics piping systems for drainage and sewerage with or without pressure - Glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) - Specifications for pipes, fittings and joints; German version EN 14364:2013
Kunststoff-Rohrleitungssysteme für Abwasserleitungen und -kanäle mit oder ohne Druck - Glasfaserverstärkte duroplastische Kunststoffe (GFK) auf der Basis von ungesättigtem Polyesterharz (UP) - Festlegungen für Rohre, Formstücke und Verbindungen; Deutsche Fassung EN 14364:2013
Overview
This European Standard has been prepared by CEN/TC 155 "Plastics piping systems and ducting systems" the secretariat of which is held by NEN (Netherlands). The preliminary work was carried out by CEN/TC 155/WG 14 "Systems of glass-reinforced thermosetting plastics for all applications - Polyester, epoxy and polyester resin based concrete". The responsible German standardization committee is Joint Working Committee NA 119-05-28-10 GUA "Rohrleitungssysteme aus GFK (Abwasser und Trinkwasser)" ("Pipe systems of glass-reinforced thermosetting plastics (wastewater and drinking water)") at the Water Practice Standards Committee (NAW) at DIN. Due to potentially occurring high flow velocities and a bed load, the abrasion resistance test according to DIN EN 295-3 is usually recommended in Germany. DIN 19523 - including a test method for determination of the jetting resistance - has been published in Germany due to the increased application of high-pressure flushing procedures for cleaning of drainage and sewerage. This standard specifies the required properties of a 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. The standard is applicable to pipes, fittings and their joints of nominal sizes from DN 100 to DN 4 000, which are intended to be used for the conveyance of surface water or sewage at temperatures up to 50 °C, with or without pressure.
