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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 21003-1 was prepared by 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.
ISO 21003 consists of the following parts, under the general title Multilayer piping systems for hot and cold
water installations inside buildings:
⎯ Part 1: General
⎯ Part 2: Pipes
⎯ Part 3: Fittings
⎯ Part 5: Fitness for purpose of the system
⎯ Part 7: Guidance for the assessment of conformity [Technical Specification]
NOTE ISO 21003 does not include a Part 4: Ancillary equipment, or a Part 6: Guidance for installation.

Introduction
The system standard of which this is Part 1 specifies the requirements for a multilayer piping system.
The multilayer piping system is intended to be used for hot and cold water installations inside buildings.
In respect of potentially adverse effects on the quality of water intended for human consumption caused by the
products covered by ISO 21003:
⎯ no information is provided as to whether the products 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 these products remain in force.
Requirements and test methods for components of the piping system are specified in ISO 21003-2 and
ISO 21003-3. Characteristics relating to fitness for purpose (mainly for joints) are covered in ISO 21003-5.
ISO/TS 21003-7 gives guidance on the assessment of conformity.
This part of ISO 21003 specifies the general aspects of multilayer piping systems.
For ancillary equipment, separate standards can apply.
Guidance on installation of plastics piping systems made from various materials intended to be used for hot
and cold water installations is given in ENV 12108.
Other system standards which, at the date of publication of this part of ISO 21003, had been published for
plastics piping systems used for the same application are listed in Annex A.

INTERNATIONAL STANDARD ISO 21003-1:2008(E)

Multilayer piping systems for hot and cold water installations
inside buildings —
Part 1:
General
1 Scope
This part of ISO 21003 specifies the general aspects of multilayer piping systems intended to be used for hot
and cold water installations inside buildings for the conveyance of water — whether or not the water is
intended for human consumption (domestic systems) or heating systems — under specified design pressures
and temperatures appropriate to the class of application (see Table 1).
ISO 21003 is a reference product standard (see 3.4.3). It is applicable to multilayer pipes, fittings, their joints,
and also to joints with components made of other plastics and non-plastics materials intended to be used for
hot and cold water installations. This part of ISO 21003 is intended for use only in conjunction with all the
other parts of ISO 21003.
ISO 21003 applies only to multilayer pipes with their inner layer made of plastics.
It covers a range of service conditions (application classes) and design pressures. It is not applicable for
values of design temperature, T , maximum design temperature, T , and malfunction temperature, T , in
D max mal
excess of those in Table 1.
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects,
taking into account their particular requirements and any relevant national regulations and installation practices or codes.
