Plastics piping systems for soil and waste discharge (low and high temperature) within the building structure - Unplasticized poly(vinyl chloride) (PVC-U) - Part 1: Specifications for pipes, fittings and the system
Abstract
This document specifies the requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems intended for soil and waste discharge applications (low and high temperature): - inside buildings (application area code “B”), above ground inside the building, or outside buildings fixed onto the wall ; - for both inside buildings (application area code “B”) and buried in ground within the building structure (application area code “D”) , which is reflected in the marking by “BD”. This intended use is only applicable for components with nominal outside diameters equal to or greater than 75 mm. NOTE 1 Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 1453-1 [1]. NOTE 2 EN 476 [2] specifies the general requirements for components used in discharge pipes, drains and sewers for gravity systems. Pipes and fittings conforming to EN 1329-1 fully meet the EN 476 requirements. PVC-U pipes, fittings and the system complying with this document are suitable for the following purposes: - ventilating part of the pipework in association with discharge applications; - rainwater pipework within the building structure. This document covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations concerning colours. Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex B can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Table 27.
