Abstract The effect of instrument compliance on ERD and forced oscillation experiments is examined. A relationship for the determination of correct experimental conditions in ERD measurements is presented. It is concluded that the applicability of shear compliance corrections is doubtful whenever their magnitude is over 50% of the measured quantity and |G *| 〉 5 × 105 Pa. Compressive compliance is found to have a negligible effect in all practical cases. Torsional compliance can be important in oscillatory experiments when sample torsional stiffness is high relative to instrument stiffness. Numerical values for Rheometrics equipment are used throughout the discussion.
