Foreword
This European Standard has been prepared by Technical Committee CEN/TC 155 "Plastics piping
systems and ducting systems", the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2002, and conflicting national standards shall
be withdrawn at the latest by July 2003.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Czech
Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
This standard is a Part of a System Standard for plastics piping systems of a particular material for a
specified application. There are a number of such System Standards.
System Standards are based on the results of the work undertaken in ISO/TC 138 "Plastics pipes,
fittings and valves for the transport of fluids", which is a Technical Committee of the International
Organization for Standardization (ISO).
They are supported by separate standards on test methods to which references are made throughout
the System Standard.
The System Standards are consistent with general standards on functional requirements and on
recommended practice for installation.
EN 1456 consists of the following parts, under the general title Plastics piping systems for buried and
above-ground drainage and sewerage under pressure Unplasticized poly(vinyl chloride) (PVC-U):
Part 1: Specifications for piping components and the system (the present standard)
Part 2: Guidance for the assessment of conformity (ENV)
This standard includes the following:
Annex A (informative): Guidance for installation
Bibliography
At the date of publication of this standard, System Standards for piping systems of other plastics
materials used for the same application are the following:
NOTE All listed System Standards are under preparation.
Plastics piping systems for pressure and non-pressure underground drainage and sewerage -
Glass-reinforced thermosetting plastics (GRP) based on polyester resin (UP)

general purposes, drainage and sewerage - Polyethylene (PE)
Introduction
This standard specifies the requirements for a piping system and its components made from
unplasticized poly(vinyl chloride) (PVC-U). The piping system is intended to be used for buried and
above-ground drainage and sewerage under pressure.
Since the differences between requirements for piping components according to EN 1452 and this
standard are slight, this standard gives only specific requirements, which are applicable to drainage

and sewerage under pressure. For all aspects common to water supply, reference is made to
EN 1452.
This standard is therefore complementary to, and can only be used in conjunction with, EN 1452,
Parts 1 to 5 and ENV 1452-6.
When EN 1452 is taken into account, the medium "water" for the pipes, fittings, valves and ancillary
equipment needs to be read as "sewage and drainage".
Clause 3 of this standard covers the general aspects of the plastics piping system. Components,
requirements and test methods are specified in clauses 4, 5 and 6 of this standard. Characteristics for
fitness for purpose (mainly for joints) are covered in clause 7. Guidance for installation is given in
Annex A.
1 Scope
This European Standard specifies requirements for unplasticized poly(vinyl chloride) (PVC-U) piping
systems in the field of buried and above-ground drainage and sewerage under pressure.
In conjunction with one or more of Parts 1 to 5 of EN 1452 and ENV 1452-6, it is applicable to PVC-U
pipes, fittings, valves and ancillary equipment, their joints and to joints with components of other
plastics and non-plastics materials intended to be used for the conveyance of sewage and drainage
under pressure at approximately 20 °C as follows:
a) buried in the ground;
b) sea outfalls;
c) laid in inland waters and/or in ducts;
d) suspended below bridges.
This standard is also applicable to components for the continuous conveyance of sewage and
[1]
drainage up to and including 45 °C as required in EN 773 .
NOTE 1 In this case the pressure derating factors given in EN 1452-2:1999, Figure A.1 apply.
NOTE 2 No pressure reduction is necessary for the drainage of waste waters at short-term peak temperatures up to 45 °C
(cumulated for 2 years during a service life of 50 years).

This European Standard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of any

For the purposes of this standard, the definitions, symbols and abbreviations given in parts 1 to 5 of
EN 1452:1999 apply, as applicable.
3.2 Material
3.2.1 PVC-U compound
The material from which the pipes, fittings and valves are made shall be an unplasticized poly(vinyl
chloride) compound. This compound shall consist of PVC-U resin, to which are added those additives
that are needed to facilitate the manufacture of pipes, fittings and valves conforming to this standard.
None of these additives shall be used separately or together in quantities sufficient to impair the
fabrication or solvent cementing properties of the product or to impair the chemical and physical or
mechanical properties (in particular long-term mechanical strength and impact strength) as specified
in this standard.
3.2.2 Reprocessable and recyclable materials
The use of the manufacturer's own reprocessable material obtained during the production and works
testing of products conforming to this standard is permitted in addition to the use of virgin material.
Reprocessable material obtained from external sources and recyclable material shall not be used.
3.2.3 Chemical resistance
In cases where piping systems conforming to this standard will be used for chemically contaminated
waste waters, such as industrial discharges, chemical and temperature resistance shall be taken into
account.
1) In ISO/TC138/SC5 a new extrapolation method is under development, which is intended to replace

from the LCL in accordance with EN ISO 12162:1995.
The pipe material shall be classified by the compound manufacturer.
NOTE Where there is available long-term experience with the effect of a change in material/compound, it is not
necessary to re-evaluate the MRS. In this case the values determined with five test pieces at 20 °C and 60 °C during 1000 h to
5000 h are located on or above the 97,5 % LCL long-term characteristic curve established prior to the material/compound
change.

1) To apply an overall service (design) coefficient of 2,5 (instead of 2,0) for pipes with nominal diameters
above 90 mm, the next higher pressure rating, PN, shall be chosen.

NOTE 1 The nominal wall thicknesses conform to ISO 4065:1996 .
NOTE 2 The PN 6 values for S 20 and S 16 are calculated with the preferred number 6,3.
NOTE 3 The pipe series S 16,7 is intended to be phased out by the end of [DAV + 2 years].
