European foreword
This document (prEN 1329-1:2019) has been prepared by Technical Committee CEN/TC 155 “Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
This document will supersede EN 1329-1:2014+A1:2018.
The main changes compared to the previous edition are:
— review of non-virgin material use and alignment with recently revised EN 1401-1;
— updating in accordance with the latest template;
— updating of normative references.
EN 1329 consists of the following parts, under the general title 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;
— Part 2: Guidance for the assessment of conformity (technical specification).

1 Scope
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” or “BD”.
NOTE 2 Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by
EN 1453-1 [1].
NOTE 3 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 4 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 method 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 5 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.
For external above ground application additional requirements depending on the climate should be
agreed between the manufacturer and the user.
NOTE 6 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 6 and to the requirements of Table 25.
