1 Scope
This document specifies the test conditions for the determination of the tensile properties
of isotropic and orthotropic fibre-reinforced plastic composites, based upon the general
principles given in ISO 527-1.
NOTE 1 Unidirectional reinforced materials are covered by ISO 527-5.
The methods are used to investigate the tensile behaviour of the test specimens and
for determining the tensile strength, tensile modulus, Poisson's ratios and other
aspects of the tensile stress-strain relationship under the defined conditions.
The test method is suitable for use with the following materials:
— fibre-reinforced thermosetting and thermoplastic composites incorporating non-unidirectional
reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combinations
of such reinforcements, hybrids, rovings, short or milled fibres or preimpregnated
materials (prepregs);
NOTE 2 Injection moulded specimens are covered by ISO 527-2.
— combinations of the above with unidirectional reinforcements and multidirectional
reinforced materials constructed from unidirectional layers, provided such laminates
are symmetrical;
