What is the limit for friability of tablets?

Answer Posted / aimsizer

Friability test limits is that if obviously cracked, cleaved, or broken tablets are present in the tablet sample after tumbling, the sample fails the test. If the results are doubtful or if the weight loss is greater than the targeted value, the test should be repeated twice and the mean of the three tests determined. A maximum mean weight loss from the three samples of not more than 1.0% is considered acceptable for most products. Conventional compressed tablets that lose less than 0.5% to 1% of weight are considered acceptable, less than 0.5% shows superior friability of tablets.
