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.
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.
International Standard ISO 6259-1 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.
ISO 6259 consists of the following parts, under the general title
Thermoplastics pipes — Determination of tensile properties:
— Part 1: General test method
— Part 2: Pipes made of unplasticized poly(vinyl chloride) (PVC-U),
chlorinated poly(vinyl chloride) (PVC-C) and high-impact poly(vinyl
chloride) (PVC-HI)
— Part 3: Polyolefin pipes

Introduction
This part of ISO 6259 specifies a short-term tensile test method for
determining the tensile properties of thermoplastics pipes.
It can provide data for further testing for the purpose of research and
development.
It cannot be regarded as significant for applications in which the conditions
of application of the force differ considerably with those in this test method,
such applications requiring the appropriate impact, creep and fatigue tests.
The tests of tensile properties should be principally regarded as tests of
material in the form of pipe. The results can be useful as a material process
control test, but are not a quantitative assessment of long term pipe
performance.
ISO 6259 has been drawn up on the basis of ISO 527.
For ease of use, it has been thought preferable to draw up a complete
document that can be used for determining the tensile properties of
thermoplastics pipes. For greater detail, reference should be made to
ISO 527.
It should however be noted that ISO 527 is applicable to materials in sheet
form, whereas ISO 6259 is applicable to materials in pipe form.
As it was considered essential to test the pipes as supplied, i.e. without
reduction in thickness, difficulties are those in the choice of test piece.
ISO 527 specifies test pieces a few millimetres thick, whereas the
thickness of a pipe can be up to around 60 mm. This is why certain
changes have been made on this point.
For thin-walled pipes, the test piece can be obtained by die cutting, while
for thick pipes, it can be obtained only by machining.
At present, ISO 6259 comprises three parts. The first part gives the general
conditions under which the tensile properties of thermoplastics pipes are to
be determined. The other two parts provide, respectively, particular
information on the execution of tests on pipe made from different materials
(see the foreword).
The basic specifications for the various materials are given in informative
annexes in the relevant parts.

Thermoplastics pipes — Determination of tensile properties —
Part 1:
General test method
1 Scope
This part of ISO 6259 specifies a method of determining the tensile properties of thermoplastics pipes, including in
particular the following properties:
— stress at yield point;
— elongation at break.
This part of ISO 6259 is applicable to all types of thermoplastics pipe, regardless of their intended use.

3 Principle
Test pieces of given shape and dimensions are obtained from a thermoplastics pipe, in the longitudinal direction, by
cutting or machining.
The tensile properties are measured using a test machine under specified conditions.
