Overview

EN ISO 6259-1:2015 (CEN endorsement of ISO 6259-1:2015) specifies a general, short‑term tensile test method for determining the tensile properties of thermoplastics pipes. The standard covers laboratory procedures to obtain stress at yield and elongation at break for pipe specimens and is applicable to all types of thermoplastic piping regardless of intended use. It is intended primarily as a material and process control or R&D test and is not a substitute for long‑term performance tests (impact, creep, fatigue).

Key topics and requirements

• Scope and applicability: Test method applies to thermoplastics pipes in pipe form (not sheet) and is the general method used across the ISO 6259 series.
• Test principle: Short‑term tensile testing of specimens taken from pipes to measure stress at yield and elongation at break.
• Specimen preparation: Guidance on types of test pieces, sampling from pipes, selection and checking of specimens; special considerations for thin‑walled vs. thick pipes.
• Apparatus and conditioning: References to required tensile testing equipment and conditioning of specimens prior to test.
• Test execution: Instructions on test speed, procedure, and measurement of gauge length and cross‑section.
• Results and reporting: Expression of results (stress at yield, elongation at break), statistical parameters, rules for retests and the required contents of the test report.
• Limitations: Not adequate by itself for predicting long‑term pipe performance; derived from ISO 527 but adapted for pipe geometries.

Applications and who uses it

• Manufacturers of thermoplastic pipes using ISO 6259-1 for quality control and batch acceptance.
• Test laboratories performing standardized tensile testing and issuing conformity reports.
• R&D teams evaluating material formulations, processing effects and mechanical performance of pipe products.
• Technical specifiers, procurement officers and compliance managers referencing tensile properties in product standards and contracts.
• Regulators and standards developers integrating tensile property requirements into piping system standards.

Practical value

• Provides repeatable, comparable tensile property data for material selection and process control.
• Helps detect manufacturing defects or material inconsistencies that affect yield strength and ductility.
• Supports product development and benchmarking across thermoplastic materials and pipe dimensions.

• ISO 6259 series: Part 2 (PVC variants), Part 3 (polyolefins)

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

ISO 6259-1:2015(E)
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 as applications requiring the appropriate impact,
creep, and fatigue tests.
The tests of tensile properties are intended to 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.
[1][2]
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 can be made to
[1][2]
ISO 527.
[1][2]
However, let it 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.
[1][2]
ISO 527 specifies test pieces a few millimetres thick, whereas the thickness of a pipe can be in
excess of 50 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 releva
