Plastics — Determination of dynamic mechanical properties — Part 12: Compressive vibration — Non-resonance method

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).
