What is this standard about?

This document describes a flexural, non-resonance method for determining the components of the flexural complex modulus Ef* of polymers at frequencies typically in the range 0,01Hz to 100Hz. Higherfrequency measurements can be made, but significant errors in the dynamic properties measured are likely to result. The method is suitable for measuring dynamic storage moduli in the range 10 MPa to 200 GPa.

This method is particularly suited to the measurement of loss factors greater than 0,02 and can therefore 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). The availability of data determined over wide ranges of both frequency and temperature enables master plots to be derived, using frequency/temperature shift procedures, which present dynamic properties over an extended frequency range at different temperatures.
