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 1452-3 was prepared by the European Committee for 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

Introduction
The System Standard, of which this is Part 3, specifies the requirements for a piping system and its
components made from unplasticized poly(vinyl chloride) (PVC-U). The piping system is intended to be used
for water supply and for buried and above-ground drainage and sewerage under pressure.
In respect of potential adverse effects on the quality of water intended for human consumption, caused by the
products covered by this part of ISO 1452, the following are relevant.
a) This part of ISO 1452 provides no information as to whether the products may be used without restriction.
b) Existing national regulations concerning the use and/or the characteristics of these products remain in
force.
Requirements and test methods for material and components, other than fittings, are specified in ISO 1452-1,
ISO 1452-2 and ISO 1452-4. Characteristics for fitness for purpose (mainly for joints) are established in
ISO 1452-5.
This part of ISO 1452 specifies the characteristics of fittings.
[1]
Guidance for installation is given in ISO/TR 4191 .

Guidance for the assessment of conformity is provided in ENV 1452-7 .
For the convenience of users of this part of ISO 1452, marking on fittings and flanges according to withdrawn
International Standards (e.g. ISO 4422-3:1996) may be considered valid for a period, e.g. up to three years
from the date of publication of this part of ISO 1452.

sewerage under pressure.
It also specifies the test parameters for the test methods referred to in this part of ISO 1452.
In conjunction with ISO 1452-1, ISO 1452-2 and ISO 1452-5, it is applicable to PVC-U fittings and to joints
with components of PVC-U, other plastics and non-plastics materials intended to be used for the following:
a) water mains and services buried in the ground;
b) conveyance of water above ground for both outside and inside buildings;
c) buried and above-ground drainage and sewerage under pressure.
It is applicable to fittings in piping systems intended for the supply of water under pressure up to and including
25 °C (cold water), intended for human consumption and for general purposes as well as for waste water
under pressure.
This part of ISO 1452 is also applicable to components for the conveyance of water and waste water up to
and including 45 °C. For temperatures between 25 °C and 45 °C, Figure A.1 of ISO 1452-2:2009 applies.
NOTE 1 The producer and the end-user can come to agreement on the possibilities of use for temperatures above
45 °C on a case-by-case basis.
Depending on the jointing method, this part of ISO 1452 is applicable to the following types of fittings:
⎯ fittings for solvent cementing;
⎯ elastomeric ring seal fittings.
PVC-U fittings can be manufactured by injection-moulding and/or be fabricated from pipe.
This part of ISO 1452 is also applicable to PVC-U flange adapters and to the corresponding flanges made
from various materials.
This part of ISO 1452 covers a range of fitting sizes and pressure classes and gives requirements concerning
colours.
NOTE 2 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.

The nominal inside diameter(s), d , of a fitting shall correspond to, and be designated by, the nominal outside
n
diameter(s) of the pipe(s) for which the fitting is designed.
6.3 Fittings for solvent cementing
6.3.1 Socket and spigot dimensions
The socket dimensions of the fittings shall be the same as for sockets on pipes and shall conform to
ISO 1452-2:2009.
The spigot length(s) shall be at least equal to the corresponding socket length(s).

The tolerance on the diameter of the spigot ends, d , of reducing bushes (see Table 7) shall always be

positive and be as follows:
⎯ maximum 0,2 mm for diameters equal to or less than 90 mm;
⎯ maximum 0,3 mm for diameters 110 mm to 160 mm;
⎯ maximum 0,4 mm for diameters 180 mm to 225 mm;
⎯ maximum 0,5 mm for diameters 250 mm to 315 mm.
6.3.2 Diameters, laying lengths, bend radii and angles
6.3.2.1 For the following types of injection-moulded fittings, the Z-lengths shall be calculated using one of
Equations (1), (2), (3), (4), (5), (6), (7) or (8), as applicable, where α is the angle of the elbow and r is the
radius of the bend.

The calculated values are given in Table 1 to Table 7. The calculated values may be adapted by the
manufacturer.
The manufacturer's information (e.g. catalogues) shall state the exact value(s) of the Z-length(s).
The deviation from the calculated values are recommended to be not greater than the values given in Table 1,
Table 2, Table 5, Table 6 and Table 7, as applicable.
6.3.2.2 For bends made from pipe, the Z-design-lengths, Z , and the bend radii shall be equal to or
d
greater than the values given in Table 3 and Table 4, as applicable.
NOTE 1 The Z -lengths are always greater than the corresponding socket lengths.
d
The wall thickness in the bend area of bends made from pipe shall be not less than the specified minimum
wall thickness for the corresponding pipe given in ISO 1452-2.
NOTE 2 If needed, the next pipe series with the smaller S-number can be used. See also 7.2.
