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.
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 13260 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids, Subcommittee SC 1, Plastics pipes and fittings for soil, waste and drainage (including land
drainage).

INTERNATIONAL STANDARD ISO 13260:2010(E)

Thermoplastics piping systems for non-pressure underground
drainage and sewerage — Test method for resistance to
combined temperature cycling and external loading
1 Scope
This International Standard specifies two methods for testing pipes and fittings or joints for plastics piping
systems intended for use in underground drainage and sewerage systems for their resistance to deformation
and leakage, when subjected to sustained external loading in conjunction with the passage of hot water.
Method A involves temperature cycling, by passing hot water and cold water alternately, and is applicable to
pipes and associated fittings having a mean outside diameter d u 190 mm.
em
Method B involves passing hot water only, except at intervals specified for measurement of internal
deflection, and is applicable to pipes and associated fittings having a mean outside diameter
190 mm < d u 510 mm.

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 48, Rubber, vulcanized or thermoplastic — Determination of hardness (hardness between 10 IRHD and
100 IRHD)
3 Principle
A test piece comprising a pipe or an assembly of pipe(s) and fitting(s) is placed on a 100 mm gravel bed and
covered with gravel to 600 mm above the crown of the pipe confined by a box of specified dimensions.
Depending on the nominal size of the largest pipe or joint under test, a constant vertical load is applied via the
gravel and either a specified number of cycles of hot and cold water or just hot water is passed through the
test piece. The deformation of the test piece, as indicated by vertical deflection or internal diametric
compression, is measured.
For sizes having a mean outside diameter d u 190 mm, hot and cold water is passed through the test piece
em
and air may be blown through the test piece during the intervals between stages (Method A).
For pipes with a mean outside diameter 190 < d u 510 mm a constant flow of hot water is passed through
em
the test piece (Method B).
Vertical deflection of the test piece is measured. The test piece is checked at the end of the test for cracking,
for local deflection in the bottom of the main channel and for leakage at the joints.

It is assumed that the following parameters are set by the referring standard:
a) if appropriate, the limits of the temperature of the water flowing out (see 7.2.2);
b) if appropriate, the duration of the flow (see 7.2.2);
c) the percentage, x, of d for the calculation of the diameter of the hard ball, in accordance with 7.3.3.

The inside box width shall be determined on the basis of a clearance of
(350 ± 100) mm between the side of the pipe/fitting and the side of the box. The inside box
width should be adjustable by closing the gap using plywood sheeting or brickwork as a
spacer.

The inside walls of the box shall be vertical ±3 mm and shall have an inside smooth surface, e.g. plywood or
flat sheet.
The box shall be constructed and reinforced such that, when under load, it shall not deflect more than 3,0 mm
at any point.
The pipe line shall pass through the walls of the box via holes sealed in such a way as to impose minimal
restraint on the assembly (see Clause 5), e.g. by flexible closed cell sponge collars. The test assembly of
pipes or pipes and fittings shall be placed with a fall of between 1:100 and 1:75 to the horizontal base, such
that in the case of Method A, conditions alternate between discharges of hot and cold water or in the case of
Method B, water at a constant temperature can be passed through the assembly while it is subjected to a
constant force acting through the gravel.
The box shall be constructed such that it can accommodate a total height of gravel of 600 mm above the
crown of the pipe.
