Plastics piping systems for hot and cold water installations — Polyethylene of raised temperature resistance (PE-RT) — Part 5: Fitness for purpose of the system
ISO 22391-5:2007 specifies the characteristics of the fitness for purpose of piping systems made from polyethylene of raised temperature resistance (PE-RT), 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) or heating systems -- under the design pressures and temperatures appropriate to the class of application according to ISO 22391-1. It covers a range of service conditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and test methods. When used in conjunction with the other parts of ISO 22391, it is respectively applicable to PE-RT pipes, fittings, their joints, and to joints having components of PE-RT as well as of other plastics and non-plastics materials, used for hot and cold water installations. It is not applicable for values of design temperature, maximum design temperature or malfunction temperature in excess of those specified in ISO 22391-1.

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 22391-5 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 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
⎯ Part 2: Pipes
⎯ Part 3: Fittings
⎯ Part 5: Fitness for purpose of the system

Introduction
ISO 22391, the system standard, 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:
a) no information is provided as to whether the products may 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 characteristics of fitness for purpose of the system. At the time of its
publication, system standards for piping systems of other plastics materials used for the same application are
⎯ ISO 15874:2003, Plastics piping systems for hot and cold water installations — Polypropylene (PP),
⎯ ISO 15875:2003, Plastics piping systems for hot and cold water installations — Crosslinked polyethylene
(PE-X),
⎯ ISO 15876:2003, Plastics piping systems for hot and cold water installations — Polybutylene (PB), and
⎯ ISO 15877:2003, Plastics piping systems for hot and cold water installations — Chlorinated
poly(vinyl chloride) (PVC-C).

INTERNATIONAL STANDARD ISO 22391-5:2007(E)
Plastics piping systems for hot and cold water installations —
Polyethylene of raised temperature resistance (PE-RT) —
Part 5:
Fitness for purpose of the system
1 Scope
This part of ISO 22391 specifies the characteristics of the fitness for purpose of piping systems made from
polyethylene of raised temperature resistance (PE-RT), 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) or heating systems — under the design pressures and temperatures
appropriate to the class of application according to ISO 22391-1.
It covers a range of service conditions (classes of application), design pressures and pipe dimension classes,
and also specifies test parameters and test methods. When used in conjunction with the other parts of
ISO 22391, it is respectively applicable to PE-RT pipes, fittings, their joints, and to joints having components
of PE-RT as well as of other plastics and non-plastics materials, used for hot and cold water installations.
It is not applicable for 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.
