Plastics - Determination of dynamic mechanical properties - Part 2: Torsion-pendulum method
Specifies two methods 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. Also provides information concerning the onset of plastic flow.
