FRIABILITY
A tablet’s strength has a significant impact on its marketing, transportation and dissolution. The mechanical strength of tablet or granules can be determined by its hardness and through friability test. A clear synthetic polymer drum with polished internal surfaces that is not susceptible to static buildup shouldbe used; it should have an internal diameter of 283 to 291 mm and a depth of 36 to 40 mm. The drum has a detachable side. A curving projection that runs from the center of the drum to the outside wall and has an inside radius of 75.5 to 85.5 mm tumbles the tablets with each rotation of the drum. A device that revolves at 25 ±1 rpm has the drum fixed to its horizontal axis. As a result, the tablets slide or roll during every rotation, landing on the drum wall or one another.
