This document defines hardness of water as the property of water to form an insoluble curd with soap instead of lather due to the presence of calcium, magnesium, bicarbonates, sulfates and chlorides. .Tablet hardness testers only provide accurate and reliable results if the mechanical components and electronics of the tester fulfilla whole set of design requirements. When comparing results from different testers, it is important to look at how the testers meet these requirements in order to identify possible reasons for variations. Brinell Hardness test is best for measuring hardness of Grey C.I. casting consisting of soft flake graphite, iron & hard iron carbide. The main drawback of the Brinell test is the need to optically measure the indent size. This requires that the test point be finished well enough to make an ac- curate measurementPrepared by, (1) PATEL SHREY B . 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.
Friability test of uncoated tablets. Friability testing is used to test the durability of tablets during transit (packing, transportation). Measurement of tablet friability supplements other physical strength measurements, such as tablet breaking force. It is a pharmacopoeial test for the evaluation of tablets or quality control tests of tablets.There are many different standards, both ASTM & ISO that cover the requirements of calibration of various hardness testers.
