This document describes a compressive vibration, non-resonance method for determining the components of the compressive complex modulus E* of polymers at frequencies typically in the range 0,01 Hz to 100 Hz. The method is applicable for measuring dynamic storage moduli of semi-rigid polymers in the range 1 MPa to 1 GPa.

This method is particularly suited to the measurements of dynamic moduli and loss factors of semi-rigid plastics in the shape of a right-angled prism, cylinder or tube and can be conveniently used to study the variation of dynamic properties with temperature and frequency through most of the glass-rubber relaxation region (see ISO 6721-1).
