Document Type and Number:
Japanese Patent JP2001507462
Kind Code:
A
Abstract:
The invention relates to a method and a device for conducting a hardness test on test specimens (7, 7', 7'', 28, 28'), specially tablets. The direction in which the hardness test is conducted by pressing a pressure piston (3, 3', 3'', 26, 26') and a thrust bearing (4, 4', 4'', 27, 27') against each other, is actively adjusted to the preferred axis (12, 2', 12'') of the test specimen (7, 7', 7'', 28, 28'). This enables measurement errors to be avoided, specially in relation to asymmetrical test specimens, resulting from variations in the direction of testing (13, 13'). The position and orientation of the test specimen (7, 7', 7'', 28, 28') are detected by means of a position signaling device (10). Subsequently, the testing direction (13) is adjusted to the preferred axis (12, 12', 12'') by actively rotating the pressure piston (3, 3', 3'', 26, 26') and the thrust bearing (4, 4', 4'', 27, 27') on a stationary test bench (1, 1', 1'', 32, 32') and a stationary test specimen (7, 7', 7'', 28, 28').
