This Technical Specification (CEN/TS) was approved by CEN on 14 November 2011 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
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/TS 22391-7 was prepared by the European Committee for Standardization (CEN) Technical Committee
TC 155, Plastics piping 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).
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
At the date of publication of this part of ISO 22391, System Standards 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)
Figures 1 and 2 are intended to provide general information on the concept of testing and organization of
those tests used for the purpose of the assessment of conformity. For each kind of test, i.e. type test (TT),
batch release test (BRT), process verification test (PVT), and audit test (AT), this part of ISO 22391 details the
applicable characteristics to be assessed as well as the frequency and sampling of testing.
A typical scheme for the assessment of conformity of pipes, fittings or assemblies by manufacturers is given in
Figure 1.
