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 527-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.
This second edition cancels and replaces the first edition (ISO 527-2:1993), which has been technically revised.
ISO 527 consists of the following parts, under the general title Plastics — Determination of tensile properties:
— Part 1: General principles
— Part 2 :Test conditions for moulding and extrusion plastics
— Part 3: Test conditions for films and sheets
— Part 4: Test conditions for isotropic and orthotropic fibre-reinforced plastic composites
— Part 5: Test conditions for unidirectional fibre-reinforced plastic composites

INTERNATIONAL STANDARD ISO 527-2:2012(E)
Plastics — Determination of tensile properties —
Part 2:
Test conditions for moulding and extrusion plastics
1 Scope
1.1 This part of ISO 527 specifies the test conditions for determining the tensile properties of moulding and
extrusion plastics, based upon the general principles given in ISO 527-1.
1.2 The methods are selectively suitable for use with the following range of materials:
— rigid and semi-rigid thermoplastics moulding, extrusion and cast materials, including compounds filled
and reinforced by, for example, short fibres, small rods, plates or granules but excluding textile fibres (see
ISO 527-4 and ISO 527-5). See ISO 527-1:2012, Clause 3 for the definition of “rigid” and “semi-rigid”.
— rigid and semi-rigid thermosetting moulding and cast materials, including filled and reinforced compounds
but excluding textile fibres as reinforcement (see ISO 527-4 and ISO 527-5);
— thermotropic liquid crystal polymers.
The methods are not normally suitable for use with rigid cellular materials or sandwich structures containing
cellular material. For rigid cellular materials see ISO 1926.
The methods are not suitable for flexible films and sheets, of thickness smaller than 1 mm, see ISO 527-3.
1.3 The methods are applied using specimens which may be either moulded to the chosen dimensions or
machined, cut or punched from injection- or compression-moulded plates. The multipurpose test specimen is
preferred (see ISO 20753).
