This document specifies the general principles of a method for determining the dynamic rheological properties of polymer melts at angular frequencies typically in the range of 0,01rads-1 to 100rads-1 by means of an oscillatory rheometer with a parallel-plate or a cone-and-plate geometry. Angular frequencies outside this range can also be used.

The method is applicable for determining values of the following dynamic rheological properties: complex shear viscosityη*, dynamic shear viscosityη', the out-of-phase component of the complex shear viscosity η”, complex shear modulusG*, shear loss modulusG”, shear storage modulusG', phase angle δ, and loss factor tanδ. It is suitable for measuring complex shear viscosity values typically up to ~10MPas.

NOTE The shear loss modulusG´´ is sometimes also called viscous shear modulus and the shear storage modulusG´ is sometimes also called elastic shear modulus.
