    The tablet is pushed against a stationary anvil until it fractures. A reading is taken from a scale indicator. [5] Kraemer Elektronik's tablet testing system was the first automatic tablet hardness testing system for auto-regulation at tablet presses, invented by German mechanical engineer Mr. Norbert Kraemer in Darmstadt, Germany.

    en.wikipedia.org/wiki/Tablet_(pharmacy)

    Standards for tablet properties are published in the various international pharmacopeias (USP/NF, EP, JP, etc.). The hardness of tablets is the principal measure of mechanical strength. Hardness is tested using a tablet hardness tester. The units for hardness have evolved since the 1930s but are commonly measured in kilograms per square centimetre.

    A Persoz pendulum is a device used for measuring hardness of materials. The instrument consists of a pendulum which is free to swing on two balls resting on a coated test panel. The pendulum hardness test is based on the principle that the amplitude of the pendulum's oscillation will decrease more quickly when supported on a softer surface. The ...
