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.
This second edition cancels and replaces the first edition (ISO 22391-5:2007), 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.
1)
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

1) This System Standard does not incorporate a Part 4: Ancillary equipment or a Part 6: Guidance for installation. For
ancillary equipment, separate standards can apply. Guidance for installation of plastics piping systems made from different
materials, intended to be used for hot and cold water installations, is covered by ENV 12108.

ISO 22391-5:2009(E)
Introduction
The System Standard, of which this is Part 5, 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 characteristics of fitness for purpose of the 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:
ISO 15874 (all parts), Plastics piping systems for hot and cold water installations — Polypropylene (PP)
ISO 15875 (all parts), Plastics piping systems for hot and cold water installations — Crosslinked polyethylene
(PE-X)
ISO 15876 (all parts), Plastics piping systems for hot and cold water installations — Polybutylene (PB)
ISO 15877 (all parts), Plastics piping systems for hot and cold water installations — Chlorinated
poly(vinyl chloride) (PVC-C)
