Description

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”);
for both inside buildings and buried in ground within the building structure (application area code “BD”).

NOTE 1

The intended use is reflected in the marking of products by “B”e e e or “BD”.

NOTE 2

Application “B” covers uses above ground inside the building, or outside buildings fixed onto the wall.

NOTE 3

Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 1453-1 [ 1].

NOTE 4

For use buried in ground within the building structure are intended only those components (marked with “BD”) with nominal outside diameters equal to or greater than 75 mm.

NOTE 5

EN 476 [ 2] specifies the general requirements for components used in discharge pipes, drains and sewers for gravity systems. Pipes and fittings conforming to this standard fully meet these requirements.

This document is also applicable to PVC-U pipes, fittings and the system intended for the following purposes:

ventilating part of the pipework in association with discharge applications;
rainwater pipework within the building structure.

This document also specifies the test parameters for the test methods that are referred to.

This document covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations concerning colours.

NOTE 6

It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

NOTE 7

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.
