Plastics -- Determination of dynamic mechanical properties -- Part 10: Complex shear viscosity using a parallel-plate oscillatory rheometer
This part of ISO 6721 specifies the general principles of a method for determining the dynamic rheological properties of polymer melts at angular frequencies typically in the range 0,01 rad·s−1 to 100 rad·s−1 by means of an oscillatory rheometer with a parallel-plate geometry. Angular frequencies outside this range can also be used (see note 1). The method is used to determine values of the following dynamic rheological properties: complex shear viscosity η*, dynamic shear viscosity η′, the out-of-phase component of the complex shear viscosity η″, complex shear modulus G*, shear loss modulus G″ and shear storage modulus G′. It is suitable for measuring complex shear viscosity values typically up to approximately 10 MPa.s (see note 2).
