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 15874-3 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 15874-3:2003 and ISO 15874-3:2003/Amd
1:2007), which has been technically revised.
The following material has been revised:
— in 4.1.1, Table 1, the material PP-RCT has been included;
— in 6.2.1, Figure 1 has been simplified, and in Tables 3 and 4, the socket length and socket dimensions
of socket fusion fittings have been adjusted;
— in 6.2.2, Table 5, the socket dimensions for electrofusion fittings have been extended to 160 mm; and
— in 7.4, Tables 6, 7 and 8, values have been adjusted.

If evaluation using the method given in ISO 9080 or equivalent is available from long-term internal pressure
tests relative to extruded pipes of the same compound as used for the fitting, the relevant test temperature shall
be equal to or higher than the maximum design temperature, T , for the service condition class.

Conducted at 95 °C to match existing test facilities.
It is recommended that the nominal diameter of the injection-moulded tubular test pieces should be in the
range of the nominal diameters of fittings normally produced by the manufacturer.
4.1.2.2 Thermal stability
When testing the thermal stability by hydrostatic pressure testing in accordance with ISO 1167-1 at 110 °C for
8 760 h, using a test piece in pipe form or a fitting connected to pipes, the test piece shall withstand the test
without bursting. The test shall be conducted in water-in-air at an internal pressure equivalent to the hydrostatic
stress used in the pipe material thermal stability test.
If a fitting connected to pipes is used as a test piece and the pipe connection fails then the thermal stability test
shall be repeated using a test piece in pipe form.
4.1.3 Plastics fitting material other than PP
Plastics material, other than PP, for fittings intended to be used in PP piping systems for hot and cold water
within buildings for the conveyance of water, whether or not for human consumption (domestic systems) and
for heating systems shall conform to 4.1.2.
4.2 Metallic fitting material
Metallic material for fittings intended to be used with components conforming to ISO 15874 shall conform to the
requirements given in EN 1254-3 or EN 10088-1, as applicable.
4.3 Influence on water intended for human consumption
The material shall conform to ISO 15874-1.
5 General characteristics
5.1 Appearance
When viewed without magnification, the internal and external surfaces of fittings shall be smooth, clean and
free from scoring, cavities, and other surface defects to an extent that would prevent conformity to this standard.
The material shall not contain visible impurities. Slight variations in appearance of the colour shall be permitted.
Each end of a fitting shall be square to its axis.
5.2 Opacity
Fittings that are declared to be opaque shall not transmit more than 0,2 % of visible light when tested in
accordance with ISO 7686.
NOTE This test is not necessary when the fitting body is made from a compound already declared opaque for the
production of pipes.

6 Geometrical characteristics
6.1 General
Dimensions shall be measured in accordance with ISO 3126.
6.1.1 Nominal diameter(s)
The nominal diameter(s), d , of a fitting shall correspond to and be designated by the nominal outside diameter(s)
n
of the pipe(s) conforming to ISO 15874-2 for which they are designed.
6.1.2 Angles
The preferred nominal angles of non-straight fittings are 45° and 90°.
6.1.3 Threads
Threads used for jointing shall conform to EN 10226-1. Where a thread is used as a fastening thread for jointing
an assembly (e.g. union nuts) it shall conform to ISO 228-1 except that these requirements need not apply to
the threads used by the manufacturer to join component parts of a fitting together.
6.2 Dimensions of sockets for socket fusion and electrofusion fittings
6.2.1 Dimensions of socket fusion fitting
Socket fusion fittings shall be classified in two types as follows:
Type A Fittings intended to be used with pipes, where no external machining of the pipe is required
Type B Fittings intended to be used with pipes, where machining of the outside surface of the pipe is necessary
in accordance with the instructions of the manufacturer
The nominal diameter
