Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

ISO 15875-5 was prepared by the European Committee Standardization (CEN) Technical Committee
CEN/TC 155, Plastics pipings systems and ducting systems, in collaboration with ISO Technical Committee
ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and
fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 15875-5:2003), which has been technically
revised with the following changes:
— Scope has been specified more precisely
— Standards and their normative references have been updated
— Terms and definitions have been specified more precisely
— Clause 5.2 - Thermal cycling test has been adopted for bigger dimensions up to DN 250

Introduction
The System Standard ISO 15875, of which this document is Part 5, specifies the requirements for a piping
system when made from crosslinked polyehtylene (PE-X). The piping system is intended to be used for hot
and cold water installations.
In respect of potential adverse effects on the quality of water intended for human consumption, caused by
the product covered by ISO 15875 (all parts):
— ISO 15875 (all parts) provides no information as to whether the product may be used without restriction
in any of the Member States of the EU or EFTA;
— it should be noted that, while awaiting the adoption of verifiable European criteria, existing national
regulations concerning the use and/or the characteristics of this product remain in force.
Requirements and test methods for material and components of the piping system are specified in
ISO 15875-1, ISO 15875-2 and ISO 15875-3. ISO/TS 15875-7 gives guidance for the assessment of conformity.
This document specifies the characteristics of fitness for purpose of the piping systems.
At the date of publication of this standard, System Standards for piping systems of other plastics materials
used for the same application include ISO 15874, ISO 15875, ISO 15876, ISO 15877, ISO 21003 and ISO 22391.

DRAFT International Standard ISO/DIS 15875-5:2024(en)
Plastics piping systems for hot and cold water installations —
Crosslinked polyethylene (PE-X) —
Part 5:
Fitness for purpose of the system
1 Scope
This document specifies the characteristics of the fitness for purpose of crosslinked polyethylene (PE-X)
piping systems intended to be used for hot and cold water installations within buildings for the conveyance
of water whether or not intended for human consumption (domestic systems), and for heating systems,
under design pressures and temperatures appropriate to the class of application (see ISO 15875-1).
It also specifies the test parameters for the test methods referred to in this standard.
The designation crosslinked polyethylene is used together with the abbreviation PE-X throughout ISO 15875,
including this document.
ISO 15875 covers a range of service conditions (application classes), design pressures and pipe dimension
classes. For values of design temperature (T ), maximum temperature (T ), malfunction temperature
D max
(T ) and service times in excess of those defined in ISO 15875-1, this document does not apply.
mal
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these
application classes (see ISO 15875 part 1), taking into account their particular requirements and any relevant national
regulations and installation practices or codes.
The ISO 15875 standards series is a piping system standard.
This part shall only be used in conjunction with all the other parts of ISO 15875. This document is applicable
to joints between pipes conforming to ISO 15875-2 and fittings made of plastics and non-plastics materials
conforming to ISO 15875-3, for hot and cold water installations.
In order to comply with this standard all requirements of this document shall be met.
NOTE 2 The test results obtained from a specific piping system test according ISO 15875-5 cannot be transferred
to other combinations of pipes and fittings.
2 Normative references
This 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 of these publications apply to this
standard only when incorporated in it by amendment or revision. For undated references the latest edition
of the publication referred to applies (including amendments).
