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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the

ISO 15876-2 was prepared by the European Committee Standardization (CEN) Technical Committee
CEN/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).
This second edition cancels and replaces the first edition (ISO 15876-2:2003), which has been
technically revised with the following changes:
— introduction of polybutene random copolymer (PB-R) and renaming existing polybutene (PB) into
polybutene homopolymer (PB-H);
— revision of specifications for conditioning of samples.
It also incorporates the Amendment ISO 15876-2:2003/Amd 1:2007.

Introduction
The System Standard ISO 15876, of which this document is Part 2, specifies the requirements for a
piping system when made from polybutene (PB). 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 product covered by ISO 15876 (all parts):
— ISO 15876 (all parts) provides no information as to whether the product 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 this product remain in force.
Requirements and test methods for material and components, other than pipes, are specified in
ISO 15876-1 and ISO 15876-3. Characteristics for fitness for purpose (mainly for joints) are covered in
ISO 15876-5. ISO/TS 15876-7 gives guidance for the assessment of conformity.
This document specifies the characteristics of pipes.
At the date of publication of this standard, System Standards for piping systems of other plastics
materials used for the same application include ISO 15874, ISO 15875, ISO 15876, ISO 15877, ISO 21003
and ISO 22391.

Plastics piping systems for hot and cold water
installations — Polybutene (PB) —
Part 2:
Pipes
1 Scope
This document specifies the characteristics of pipes for polybutene-1 (PB-1) piping systems intended to
be used for hot and cold water installations within buildings for the conveyance of water whether or not
intended for human consumption (domestic systems), and for heating systems, under design pressures
and temperatures appropriate to the class of application (see ISO 15876-1).
The designation polybutene is used together with the abbreviation PB throughout this document.
This document covers a range of service conditions (application classes), design pressures and pipe
dimension classes. For values of T , T and T in excess of those in ISO 15876-1, this document does
D max mal
not apply.
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.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with the other parts of ISO 15876, this document is applicable to PB pipes, their joints
and to joints with components of PB, other plastics and non-plastics materials intended to be used for
hot and cold water installations.
It is applicable to pipes with or without (a) barrier layer(s).
NOTE 2 In the case of plastics pipes provided with a thin barrier layer, e.g. to prevent or greatly diminish the
diffusion of gases and the transmission of light into or through the pipe wall, the design stress requirements are
totally met by the base polymer (PB).

4 Pipe material
4.1 General
The pipe material from which the pipe is made shall comply with ISO 15876-1.
After extrusion or moulding, PB undergoes a crystalline phase transition (usually called ageing) before
it develops its final properties. The minimum required transition time depends on temperature and
product characteristics. The same final material performance is obtained once completion of crystalline
phase transition is achieved, irrespective of transition conditions. For quality control purposes,
therefore, test specimens shall be taken immediately after processing and be conditioned in accordance
with recommendations obtained from the compound supplier prior to testing.
The crystalline phase transition is dependent on time and temperature. For guidance a minimum time
of five days for PB-H and one day for PB-R should be allowed at 23 °C, unless accelerated ageing is
performed.
NOTE The crystalline phase transition can be considerably accelerated upon applying higher hydrostatic
pressure of approx. 1 kb
