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 13479 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids, Subcommittee SC 5, General properties of pipes, fittings and valves of plastic materials and
their accessories — Test methods and basic specifications.
This second edition cancels and replaces the first edition (ISO 13479:1997), which has been technically
revised.

Polyolefin pipes for the conveyance of fluids — Determination
of resistance to crack propagation — Test method for slow
crack growth on notched pipes
1 Scope
This International Standard specifies a test method for determining the resistance to slow crack growth of
polyolefin pipes, expressed in terms of time to failure in a hydrostatic pressure test on a pipe with machined
longitudinal notches in the outside surface. The test is applicable to pipes of wall thickness greater than 5 mm.

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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 161-1 and ISO 11922-1 apply.
4 Principle
Lengths of pipe with four machined longitudinal external notches are subject to a hydrostatic pressure test
whilst immersed in a water tank at 80 °C in accordance with ISO 1167-1 and ISO 1167-2. The time to failure
or test period is recorded.
NOTE It is assumed that the following test parameters are set by the standard or specification making reference to
this International Standard:
a) the number of test pieces, if applicable (see 6.5);
b) the test pressure (see 8.1);
c) the test period (see 8.1).

5 Apparatus
5.1 Pipe pressure-testing equipment, as specified in ISO 1167-1.
5.2 Notch-machining equipment, i.e. a milling machine with a horizontal mandrel rigidly fixed to the bed to
enable the pipe to be securely clamped to give a straight test piece.
The mandrel shall support the pipe bore beneath and along the full length of the notch to be machined.
The milling cutter mounted on a horizontal arbor shall be a 60° included-angle V-cutter conforming to
ISO 6108, having a cutting rate of (0,010 ± 0,002) (
