Abstract (en)
[origin: WO2011035818A1] A method for determining the hardness of solid samples and an apparatus for carrying out said method are described. In the method, a solid sample (6) is conveyed on a support (3) between breaking jaws (1) and a stop (2). The method is distinguished by the fact that a light emitter (4) emits parallel light in the direction of the solid sample (6) and a line sensor (5) detects the parallel light and/or the absence of the parallel light. The orientation of the solid sample (6) is then determined on the basis of the parallel light detected by the line sensor (5) and/or on the basis of the absence of the parallel light detected by the line sensor. The breaking jaws (1) and the stop (2) and/or the support (3) are then rotated about an axis, which runs through the support (3) and is arranged perpendicular thereto, until the breaking jaws (1) and the stop (2) have reached the position intended for measurement with respect to the solid sample (6). Finally, the hardness of the solid sample (6) is determined by moving the breaking jaws (1) towards the stop (2) and measuring the force required for this purpose.
