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 22391-3 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.
This second edition cancels and replaces the first edition (ISO 22391-3:2007), which is extended from only
dealing with PE-RT material (referred to as Type I) to cover PE-RT materials Type I and Type II.

ISO 22391 consists of the following parts , under the general title Plastics piping systems for hot and cold
water installations — Polyethylene of raised temperature resistance (PE-RT):
⎯ Part 1: General

Introduction
The System Standard, of which this is Part 3, specifies the requirements for a piping system and its
components when made from polyethylene of raised temperature resistance (PE-RT). 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
products covered by ISO 22391, the following are relevant.
a) This part of ISO 22391 provides no information as to whether the products can be used without restriction.
b) Existing national regulations concerning the use and/or characteristics of the products remain in force.
This part of ISO 22391 specifies the general aspects of the plastics piping system. At the date of publication of
this part of ISO 22391, System Standards Series for piping systems of other plastics materials used for the
same application are the following:

Fittings
1 Scope
This part of ISO 22391 specifies the characteristics of fittings for piping systems made of
⎯ polyethylene of raised temperature resistance (PE-RT), Type I, and
⎯ polyethylene of raised temperature resistance (PE-RT), Type II,
intended to be used for hot and cold water installations within buildings for the conveyance of water, whether
or not the water is intended for human consumption (domestic systems) and for heating systems, under the
design pressures and temperatures appropriate to the class of application according to ISO 22391-1.
This part of ISO 22391 covers a range of service conditions (classes of application), design pressures and
pipe dimension classes, and also specifies test parameters and test methods. In conjunction with the other
parts of ISO 22391, it is applicable to fittings made of PE-RT, as well as to those made of other materials,
intended to be fitted to pipes conforming to ISO 22391-2 for hot and cold water installations, the joints of which
are in accordance with ISO 22391-5.
This part of ISO 22391 is applicable to the following types of fitting:
⎯ mechanical fittings;
⎯ socket fusion fitting;
⎯ electrofusion fittings;
⎯ fittings with incorporated inserts.
It is not applicable to values of design temperature, maximum design temperature or malfunction temperature
in excess of those specified in ISO 22391-1.
NOTE 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.
