European foreword
This document (EN 14758-1:2023) 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 October 2023, and conflicting national standards shall
be withdrawn at the latest by October 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN EN 14758-1:2012.
The main changes compared to the previous edition are listed below:
— the Scope has been changed by introducing skin layer;
— updating of the Normative references;
— updating of the Terms and definition with the material definitions in EN 14541-1 and a new
definition of the skin;
— the Material clause has been modified by specifying the PP compound used in the skin and defining
a minimum content of mineral modifier;
— the maximum thickness of each skin has been introduced;
— the Ring stiffness class SN16 for pipes and fittings has been introduced;
— two alternatives for inside diameter of sockets has been introduced – normal and close tolerance
(CT);
— the water tightness test of fabricated fittings has been introduced;
— Annex A Utilization of reworked material and recyclate has been modified to be in line with
CEN/TS 14541-2;
— a new informative Annex D for testing of PP recyclates with the CRB-method has been added.
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.

European foreword
This document (prEN 14758-1:2021) 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 is currently submitted to the CEN Enquiry.
This document will supersede EN 14758-1:2012.
EN 14758, Plastics piping systems for non-pressure underground drainage and sewerage —
Polypropylene with mineral modifiers (PP-MD) consists of the following parts:
— Part 1: Specifications for pipes, fittings and the system;
— Part 2: Assessment of conformity (Technical Specification).
The main changes in comparison with the previous edition are:
— the Scope has been changed by introducing skin layer;
— updating of the Normative references;
— updating of the Terms and definition with the material definitions in prEN 14541-1 and a new
definition of the skin;
— the Material clause has been modified by specifying the PP compound used in the skin and defining
a minimum content of mineral modifier;
— the maximum thickness of each skin has been introduced;
— the Ring stiffness class SN16 for pipes and fittings has been introduced;
— two alternatives for inside diameter of sockets has been introduced – normal and close tolerance
(CT);
— the water tightness test of fabricated fittings has been introduced has been introduced;
— Annex A Utilization of non-virgin PE materials has been modified to be in line with
prCEN/TS 14541-2;
— a new informative Annex D for testing of PP recyclates with the CRB-method has been added.
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.

1 Scope
This document specifies the requirements for solid-wall pipes and fittings with or without internal
and/or external skin, and the system of piping systems made from mineral modified polypropylene
materials (PP-MD) in the field of 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.
NOTE 1 The skins are made of PP compound without mineral modifier.
This is reflected in the marking of products by "U" and "UD".
It also specifies the test parameters for the test methods referred to in this document.
This document covers a range of nominal sizes, a range of pipe series/stiffness classes and gives
recommendations concerning colours.
NOTE 2 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 of EN 14758 (see Foreword) it is applicable to PP-MD pipes and fittings, their
elastomeric sealing ring 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 document is applicable to PP-MD pipes with or without an integral socket.
NOTE 3 The fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings.
NOTE 4 Requirements and limiting values for application area code “D” are given in Table 4, Table 7 and
Table 13.
NOTE 5 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, when they conform to the requirements
for joint dimensions given in Clause 6 and to the requirements of Table 13.
