Mohs hardness test uses 10 reference materials of varying hardness as the scale for the test. The softest material used is talc (value=1) and the hardest material is diamond (value=10). Given that the references used for the Mohs scale do not have a graded increase, the Mohs scale lacks accuracy and is only a rough measure of hardness.4.5.4. Record the hardness value displayed on the Tablet Hardness Tester for the measured tablet. 4.5.5. Repeat the measurement process for the desired number of tablets, as per the specified test requirements. 4.6. Calculation and Interpretation of Results: 4.6.1. Calculate the average hardness value for the tested tablets. 4.6.2.
