Overview

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 tensile strength, tensile modulus and other aspects of the tensile stress/strain relationship under the conditions defined. 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 and for sandwich structures containing cellular materials. For rigid plastics, see ISO 1926. The test conditions for sandwich structures shall be agreed between experts. The methods are applied using specimens which may be either moulded to the chosen dimensions or machined, cut or punched from finished and semi-finished 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 may be used (see normative references, ISO 3167 or ISO 20753). Miniaturized test specimens are described in ISO 20753 (see normative references). 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 shall be carefully controlled and recorded. For the application of this standard, the term "tensile" has been omitted in the entire text for all stresses and strains. It shall be added, however, when indicating characteristics in order to avoid confusion with similar properties during determination of which other conditions, such as bending or compression for forming of the specimens, are applied instead of a tensile load. ISO 527-1:2012 has been prepared by ISO/TC 61/SC 2 "Mechanical properties" (secretariat: AENOR, Spain). CEN/TC 249 "Plastics", the secretariat of which is held by NBN, is responsible for the European standards. On the national level, the committee responsible for the standard is Working Committee NA 054-01-02 AA "Mechanische Eigenschaften und Probekörperherstellung" ("Mechanical properties and preparation of test specimens") of the FNK.
