2. Tablet hardness testing - Wikipedia

   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.

4. Tablet (pharmacy) - Wikipedia

   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.

5. Tableting - Wikipedia

   en.wikipedia.org/wiki/Tableting

   The physical properties of a tablet are tested either by manual or automated sampling and IPC testing (in-process control). Tablet "hardness", also called "breaking force", is tested to assure that the tablet's strength will survive all further processes, such as dedusting, coating and packaging.

7. Hardness - Wikipedia

   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 ...
