ASTM D1043 explains the determination of the stiffness characteristics of plastics over a wide range of temperatures through measuring the apparent modulus of rigidity, G, via a torsion test. The apparent modulus of rigidity may be affected by the creep characteristics of the material. Test specimen used for torsion testing per ASTM D1043 are rectangular in shape can are cut from compression molded sheets or extruded sheets of plastic.
