This European Standard specifies units made from polyester resin concrete (PRC, see 3.1.18), and their joints, for the construction of inspection chambers with inverts not exceeding 2 m deep and for manholes, intended to be used within a drain or sewer system operating without pressure. It applies to products for use outside buildings in buried installations to be installed by open-trench techniques.This document applies to nominal sizes from DN 600 to DN 3000 for chamber rings and shaft rings having a circular shape.The intended use of these products is to provide access to buried drain or sewer systems for the conveyance of wastewater, i.e. sewage, rainwater and surface water, at temperatures up to 50 °C, without pressure or occasionally at a head of pressure up to 0,5 bar ), and installed in areas subjected to vehicle and/or pedestrian traffic and outside buildings.NOTE 1The attention of readers is drawn to applicable requirements contained in EN 476.This standard specifies definitions, requirements and characteristics of units and their joints for the construction of manholes and inspection chambers, of materials, test methods, marking and evaluation of conformity.The units are classified on the basis of its type and the type of structure they are intended to be used.NOTE 2It is the responsibility of the purchaser or specifier to make the appropriate selections, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
