DIN EN 15383:2013-03

This European Standard applies to a) manholes, when made from glass-reinforced thermosetting plastics (GRP) based on polyester resin (UP); b) inspection chambers which are at a depth not exceeding 2 m. The standard applies to products, and their joints, intended for use in buried installations and to be installed by open-trench techniques. The units have a circular shape with nominal sizes not exceeding the maximum nominal size specified in EN 14364. The intended use of these products is to provide access to, buried drain or sewer systems for the conveyance of waste water at temperatures up to 50 °C, without pressure (as gravity conduits) or occasionally at a head of pressure up to 1 bar, outside buildings subjected to vehicle and/or pedestrian traffic. Committee NA 119-05-28-09 GUA "Gemeinschaftsunterausschuss NAW/FNK: Kunststoffschächte" ("Joint Subcommittee NAW/FNK: Plastic manholes") at the Water Practice Standards Committee is responsible for this standard.
