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be withdrawn at the latest by October 2023.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.
