Overview

This European Standard applies to a) manholes, when made from glass-reinforced thermosetting plastics (GRP) based on polyester resin (UP); b) inspection chambers, when made from glass-reinforced thermosetting plastics (GRP) based on polyester resin (UP) which are intended to be used with inverts 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 and installed in areas subjected to vehicle and/or pedestrian traffic. With the incorporated Amendment A1, the test temperature for the joint tests has been brought in line with the product standards for GRP pipes, EN 1796 and EN 14364. 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.
