    en.wikipedia.org/wiki/Tablet_hardness_testing

    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.

  3. Friability - Wikipedia

    en.wikipedia.org/wiki/Friability

    Friability testing is a laboratory technique used by the pharmaceutical industry to test the durability of tablets during transit. This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle. The result is inspected for broken tablets, and the percentage of tablet mass lost through chipping.

    en.wikipedia.org/wiki/Dissolution_testing

    In the pharmaceutical industry, drug dissolution testing is routinely used to provide critical in vitro drug release information for both quality control purposes, i.e., to assess batch-to-batch consistency of solid oral dosage forms such as tablets, and drug development, i.e., to predict in vivo drug release profiles.

    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.

    en.wikipedia.org/wiki/Hardness

    When testing coatings, scratch hardness refers to the force necessary to cut through the film to the substrate. The most common test is Mohs scale, which is used in mineralogy. One tool to make this measurement is the sclerometer. Another tool used to make these tests is the pocket hardness tester. This tool consists of a scale arm with ...

    en.wikipedia.org/wiki/Shore_durometer

    It was neither the first hardness tester nor the first to be called a durometer (ISV duro-and -meter; attested since the 19th century), but today that name usually refers to Shore hardness; other devices use other measures, which return corresponding results, such as for Rockwell hardness.
