1.1 This document specifies the general principles for determining the tensile properties of plastics
and plastic composites under defined conditions. Several different types of test specimen are defined to
suit different types of material which are detailed in subsequent parts of ISO 527.
1.2 The methods are used to investigate the tensile behaviour of the test specimens and for determining
the tensile strength, tensile modulus and other aspects of the tensile stress/strain relationship under the
conditions defined.
1.3 The methods are selectively suitable for use with the following materials:
— rigid and semi-rigid moulding, extrusion and cast thermoplastic materials, including filled and
reinforced compounds in addition to unfilled types; rigid and semi-rigid thermoplastics sheets
and films;
— rigid and semi-rigid thermosetting moulding materials, including filled and reinforced compounds;
rigid and semi-rigid thermosetting sheets, including laminates;
— fibre-reinforced thermosets and thermoplastic composites incorporating unidirectional or non-
unidirectional reinforcements, such as mat, woven fabrics, woven rovings, chopped strands,
combination and hybrid reinforcement, rovings and milled fibres; sheet made from pre-impregnated
materials (prepregs);
— thermotropic liquid crystal polymers.
The methods are not normally suitable for use with rigid cellular materials, for which ISO 1926 is used,
or for sandwich structures containing cellular materials.
