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 527-5 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and
reinforcement fibres.
This second edition cancels and replaces the first edition (ISO 527-5:1997), of which it constitutes a minor
revision. The main changes are as follows:
⎯ the normative references have been updated;
⎯ in 6.1.2, a thickness has been specified specifically for specimens from filament-wound test plates.
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 527-5:2009(E)

Plastics — Determination of tensile properties —
Part 5:
Test conditions for unidirectional fibre-reinforced plastic
composites
1 Scope
1.1 This part of ISO 527 specifies the test conditions for the determination of the tensile properties of
unidirectional fibre-reinforced plastic composites, based upon the general principles given in Part 1.
1.2 See ISO 527-1:1993, Subclause 1.2.
1.3 The test method is suitable for all polymer matrix systems reinforced with unidirectional fibres and which
meet the requirements, including failure mode, set out in this part of ISO 527.
The method is suitable for composites with either thermoplastic or thermosetting matrices, including
preimpregnated materials (prepregs). The reinforcements covered include carbon fibres, glass fibres, aramid
fibres and other similar fibres. The reinforcement geometries covered include unidirectional (i.e. completely
aligned) fibres and rovings and unidirectional fabrics and tapes.
The method is not normally suitable for multidirectional materials composed of several unidirectional layers at
different angles (see ISO 527-4).
1.4 The method is performed using one of two different types of test specimen, depending on the direction
of the applied stress relative to the fibre direction (see Clause 6).
1.5 See ISO 527-1:1993, Subclause 1.5.
