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.
ISO 15874-2 was prepared by Technical Committee CEN/TC 155, Plastics piping systems and ducting systems,
in collaboration with Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of
fluids, and 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 15874-2:2003 and ISO 15874-2:2003/Amd
1:2007), which has been technically revised. In Clause 6, 6.2.2, Table 5, the material PP-RCT has been
included, and Annex A, Table A.6, pipe dimensions have been extended to 160 mm.

ISO 15874 consists of the following parts under the general title Plastics piping systems for hot and cold water
installations — Polypropylene (PP):
— Part 1: General
— Part 2: Pipes
— Part 3: Fittings
— Part 5: Fitness for purpose of the system
— Part 7: Guidance for the assessment of conformity [Technical specification]

Introduction
This part of ISO 15874 specifies the requirements for a piping system when made from polypropylene (PP).
The piping system is intended to be used for hot and cold water installations.
Regarding potential adverse effects on the quality of water intended for human consumption, caused by the
product covered by ISO 15874
— no information is provided as to whether the product can be used without restriction;
— 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 15874-1
and ISO 15874-3. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 15874-5.
ISO/TS 15874-7 gives guidance for the assessment of conformity.
This part of ISO 15874 specifies the characteristics of pipes.
At the date of publication of this part of ISO 15874, the following system International Standards for piping
systems of other plastics materials used for the same application are
— ISO 15875, Plastics piping systems for hot and cold water installations — Crosslinked polyethylene (PE-X)
— ISO 15876, Plastics piping systems for hot and cold water installations — Polybutylene (PB)
— ISO 15877, Plastics piping systems for hot and cold water installations — Chlorinated poly(vinyl
chloride) (PVC-C)
— ISO 22391, Plastics piping systems for hot and cold water installations — Polyethylene of raised temperature
resistance (PE-RT)

INTERNATIONAL STANDARD ISO 15874-2:2013(E)
Plastics piping systems for hot and cold water installations —
Polypropylene (PP) —
Part 2:
Pipes
1 Scope
This part ISO 15874 specifies the requirements of pipes made from polypropylene (PP) for 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 operating pressures
and temperatures appropriate to the class of application (see ISO 15874-1:2013, Table 1).
This part of ISO 15874 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 Table 1 of ISO 15874-1:2013 do not apply.
D max mal
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 part of ISO 15874.
In conjunction with the other parts of ISO 15874, this part of ISO 15874 is applicable to PP pipes, their joints
and to joints with components of PP, 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 (PP).

3 Terms and definitions, symbols and abbreviated terms
For the purposes of this document, the terms and definitions, symbols and abbreviated terms given in
ISO 15874-1 apply.
4 Material
4.1 Pipe material
The pipe material from which the pipe is made shall comply with ISO 15874-1:2013, 5.1.
4.2 Evaluation of σ -values
LPL
The pipe material shall be evaluated in accordance with ISO 9080 or equivalent where internal pressure tests
are made in accordance with ISO 1167-1 and ISO 1167-2 to find the σ -values. The σ -value thus determined
LPL LPL
shall at least be as high as the corresponding values of the reference curves given in Figure 1, 2, 3 or 4.
NOTE One equivalent way of evaluation is to calculate the σ -value for each temperature (for example 20 °C,
LPL
60 °C and 95 °C) individually.
The reference curves in Figures 1, 2, 3 and 4 in the temperature range of 10 °C to 95 °C are derived from the
following equations:
