This International Standard specifies a method of determining the dynamic behaviour, that is the shear modulus and mechanical damping, of vulcanized rubbers over a wide temperature range at low frequencies in the range of 0.1 to 10 Hz, and comparatively low strain, less than 5x10-4 in shear, with the aid of a torsion pendulum. The test method and definitions used are in accordance with ISO 2856. The theory behind the test is also described in ISO 2856. Three methods of using a torsion pendulum are specified: Method A, in which the mass of the inertia member is supported by the test piece and the pendulum is set into free damped oscillation; Method B, in which the mass of the inertia member is supported by a fine wire suspension and the pendulum is set into free damped oscillation; Method C, which is similar to method B except that the oscillations are maintained at constant amplitude by supplying energy to the system.
