This part of ISO 527 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. The methods are used to investigate the tensile behaviour of the test specimens and for determining the strength, tensile modulus and other aspects of the stress/strain relationship under the conditions defined. The methods are selectively suitable for use with the following range of materials: - rigid and semi rigid thermoplastics (see NOTE) moulding, extrusion and cast materials, including filled an 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 thermoset and thermoplastics composites incorporating unidirectional or nonunidirectional 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 or sandwich structures containing cellular material. For rigid cellular materials see ISO 1926. Testing conditions of sandwich structures shall be agreed upon by experts. The methods are applied using specimens which may be either moulded to the chosen dimensions or machined, cut or punched from finished and semifinished products such as mouldings, laminates, films and extruded or cast sheet. The types of test specimen and their preparation are described in the relevant part of ISO 527 typical for the material. In some cases a multipurpose test specimen (See Normative references, ISO 3167 or ISO 20753) may be used. Miniaturized specimens are described in ISO 20753 (See ces) The methods specify preferred dimensions for the test specimens. Tests which are carried out on specimens of different dimensions, or on specimens which are prepared under different conditions, may produce results which are not comparable. Other factors, such as the speed of testing and the conditioning of the specimens, can also influence the results. Consequently, when comparative data are required, these factors must be carefully controlled and recorded. For the purpose of this standard, the term “tensile” has been deleted for all stresses and strains throughout the text. However, it shall be added when reporting data to avoid confusion with similar properties obtained by different modes of deformation like bending or compression.
