C.1 Relative error Fc/Fc involved in calculating the
dimensional correction factor Fc using the
approximate equations (2), (3) and (C.2) rather than
the exact equation (C.1)
Defines two methods (A and B) for determining the linear dynamic mechanical properties of plastics, i.e. the storage and loss components of the torsional modulus, as a function of temperature, for small deformations within the frequency range from 0,1 Hz to 10 Hz.
