Foreword
This document (EN 1852-1:2009) 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 September 2009, and conflicting national standards shall be
withdrawn at the latest by September 2009.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1852-1:1997.
The 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).
The System Standards 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 1852 consists of the following parts, under the general title Plastics piping systems for non-pressure
underground drainage and sewerage − Polypropylene (PP)
 Part 1: Specifications for pipes, fittings and the system (the present standard);
 Part 2: Guidance for the assessment of conformity (CEN Technical Specification);
 Part 3: Guidance for installation (CEN Technical Specification).
This part of EN 1852 includes Annex A (normative): Geometrical characteristics of pipes following S-series
11,2, Annex B (informative): General characteristics of PP pipes and fittings and Annex C (informative):
Product standards of components that can be connected to components conforming to this standard.
Plastics piping systems made of PP with mineral modifiers (PP-MD) are covered by EN 14758-1 [1].
The main change in the revised document is: EN 1852 gave wall thicknesses for two different E-modulus and
S-series, and for E-modulus above 1 700 MPa the designation PP-HM was used. In this revised document the
following changes are made:
 new S-series for SN 8 are introduced replacing the previous S-series;
 the previous S-series 11,2 for SN 8 is given in Annex A;
 new ring stiffness class SN 16 is introduced;
 the wall thickness table for fittings is modified;
 designation PP-HM is no longer used;
 impact resistance (staircase method) test temperature changed from 0 °C to −10 °C.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

1 Scope
This part of EN 1852 specifies the requirements for solid wall pipes, fittings and the system of polypropylene
(PP) piping systems intended for use for:
 non-pressure underground drainage and sewerage outside the building structure (application area code
"U"), and
 non-pressure underground drainage and sewerage for both buried in ground within the building structure
(application area code "D") and outside the building structure.
This is reflected in the marking of products by "U" and "UD".
This standard covers PP materials without mineral modifiers.
It also specifies the test parameters for the test methods referred to in this standard.
This standard covers a range of nominal sizes, and pipe series and gives recommendations concerning
colours.
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects,
taking into account their particular requirements and any relevant national regulations and installation practices or codes.
In conjunction with Part 2 and Part 3 of EN 1852 it is applicable to PP pipes and fittings, their joints and to
joints with components of other plastics and non-plastics materials intended to be used for buried piping
systems for non-pressure underground drainage and sewerage.
This standard is applicable to PP pipes and fittings with or without an integral socket.
NOTE 2 The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings.
NOTE 3 Requirements and limiting values for application area code "D" are given in Table 4, Table 7 and Table 14.
NOTE 4 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can
be connected to pipes and fittings conforming to this standard, when they conform to the requirements for joint dimensions
given in Clause 6 and to the requirements of Table 14.
