Scope

This part of ISO 6721 describes a forced, non-resonance method for determining the components of the tensile complex modulus E*of polymers at frequencies typically in the range 0,01 Hz to 100 Hz. The method is suitable for measuring dynamic storage moduli in the range 0,01 GPa to 5 GPa. Although materials with moduli outside this range may be studied, alternative modes of deformation should yield higher accuracy [i.e.a shear mode for EŒ < 0,01 GPa (see ISO 6721-6) and a flexural mode for EŒ > 5 GPa (see ISO 6721-3 or ISO 6721-5)].This method is particularly suited to the measurement of loss factors greater than 0,1 and may therefore be conveniently used t
