what is the tblet hardness,what is its unit ,we aply hydraulic pressure on tablet compression mchine but in result we gain hardness on tablet,how the pressure is converted into hardness unit. Friability refers to the ability of the compressed tablet to avoid fracture and breaking apart during transport.
Friability testing is done on all pharmaceutical tablets. The testing involves absorption rates, crushing levels and powderization, and enteric capability.
The Ability to crumble of sand is known as friability
friability F=I-F.100/I where I =Iinitial weight of tablets , F = weight after friability. Normal limit less than 1%.
