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.

The manufacturer of the compound or formulation shall confirm the MRS by testing as described in
ISO 1452-1:2009, 4.4.1, 4.4.2 or 4.4.3, respectively.
The MRS value of the fitting material shall be declared by the fitting manufacturer in its technical file.
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 part of
ISO 1452.
Each end of a fitting shall be square to its axis.
5.2 Colour
The colour of injection-moulded fittings shall be grey throughout the wall for water supply, and grey or brown
for drainage and sewerage under pressure.
The colour of fittings made from pipes shall be grey, blue or cream throughout the wall for water supply, and
grey or brown for drainage and sewerage under pressure.
5.3 Opacity of fittings intended for the above-ground conveyance of water
The wall of the fittings shall be opaque and shall not transmit more than 0,2 % of visible light when measured
in accordance with ISO 7686.
6 Geometrical characteristics
6.1 Measurement of dimensions
Dimensions shall be measured in accordance with ISO 3126.
6.2 Nominal diameters
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).

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.
