Friability test
During manufacturing and handling, tablets are subjected to
stresses from collision and tablet sliding towards one another and other solid
surfaces, which can result in the removal of small fragments and particles from
the tablet surface. The result will be progressive reduction in weight and
change in appearance.
Another application of the friability test capping or
laminate when stressed by attrition inside the rotating cylinder present in the
friability tester.
To examine this, tablets are subjected to uniform tumbling
motion for specified time and weight loss not more than 1% generally is
considered acceptable for most products.
