Why the fall height of tablet should be 6 inch during friability testing??
Friability is defined as the percentage of weight loss of powder from the surface of the tablets due to mechanical action and the test is performed to measure the weight loss during transportation .
Height of speed breaker is approx 4 inch. so 6 inch height selected for friability test.
Thanks a lot sir
The dimensions of the apparatus are “according to Pharmacopoeias” which are already harmonized regarding Friability test
