Plastics piping systems for soil and waste discharge (low and high temperature) within the building structure. Unplasticized poly(vinyl chloride) (PVC-U) -- Specifications for pipes, fittings and the system
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 piping system of unplasticized poly(vinyl chloride) (PVC-U) intended for soil and waste discharge applications (low and high temperature).
The intended uses are:
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].
PVC-U pipes, fittings and the system complying with this document are also suitable for the following purposes:
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 26.
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.
