Abstract
A method for testing samples uses a rheometer in which a measuring shaft bearing a first measuring part is rotated by a motor and the sample is introduced into a measuring gap between the first measuring part and a further measuring part. The further measuring part is mounted on a further, driven measuring shaft and the two measuring parts are rotated or oscillated at a predetermined speed independently of one another, or brought to a standstill. At the same time or in rapidly succeeding intervals during the same measuring process, the torque and the normal force are determined by a first moment detector and the first measuring unit, and the normal force exerted by the sample on the further measuring part and/or the further measuring shaft and the torque exerted on the further measuring shaft by means of a further separate motor rotating said measuring shaft are determined by means of a further measuring unit and a further moment detector and in that said simultaneously determined measured values are supplied for evaluation.
