1.1 This Part of GB/T 1040 specifies the test conditions for determining the tensile properties of moulding and extrusion plastics, based upon the general principles given in Part 1.
1.2 The methods are selectively suitable for use with the following range of materials:
— Rigid and semirigid thermoplastics moulding, extrusion and cast materials, including compounds filled and reinforced by e.g. short fibres, small rods, plates or granules but excluding textile fibres;
— Rigid and semirigid thermosetting moulding and cast materials, including filled and reinforced compounds but excluding textile fibres as reinforcement;
— Thermotropic liquid crystal polymers.
The methods are not suitable for use with materials reinforced by textile fibres, with rigid cellular materials or sandwich structures containing cellular material.
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 ISO 3167:1993, Plastics — Multipurpose test specimens).
Note: ISO 3167:1993 was replaced by ISO 3167:2002.
