1.1 This part of ISO527 specifies the test conditions for determining the tensile properties of moulding and extrusion plastics, based upon the general principles given in ISO527-1.
1.2 The methods are selectively suitable for use with the following range of materials:
-
rigid and semi-rigid thermoplastics moulding, extrusion and cast materials, including compounds filled and reinforced by, for example, short fibres, small rods, plates or granules but excluding textile fibres (see ISO527-4 and ISO527-5). See ISO527-1:2012, Clause3 for the definition of \'rigid\' and \'semi-rigid\'.
-
rigid and semi-rigid thermosetting moulding and cast materials, including filled and reinforced compounds but excluding textile fibres as reinforcement (see ISO527-4 and ISO527-5);
-
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 ISO1926.
The methods are not suitable for flexible films and sheets, of thickness smaller than 1mm, see ISO527-3.
1.3 The methods are applied using specimens which may be either moulded to the chosen dimensions or machined, cut or punched from injection- or compression-moulded plates. The multipurpose test specimen is preferred (see ISO20753).
