What is the limit for friability of tablets?
Answers were Sorted based on User's Feedback
Friability test is used to determine the physical strength 
or tablet breaking force for compressed, uncoated tablets. 
Tablet Friability Apparatus is used for the test. Remove 
any loose dust from the tablets and accurately weigh 10 
tablets. They are placed in the drum which rotates at 25±1 
rpm. Rotate the drum 100 times, and remove the tablets.
The sample fails the test, if any of the 10 tablets 
cracked, cleaved, or broken is present. If the weight loss 
is more than 1.0%, the test is repeated for twice and the 
mean of three tests is calculated. The mean not more than 
1.0% is considered acceptable.
Please note that for Effervescent tablets and chewable 
tablets the friability limits may differ.

Friability test is used to determine the physical strength
or tablet breaking force for compressed, uncoated tablets.
Tablet Friability Apparatus is used for the test. Remove
any loose dust from the tablets and accurately weigh 10
tablets or weight of the sample NLT 7 gm for small tablets. They are placed in the drum which rotates at 25±1
rpm. Rotate the drum 100 times, and remove the tablets.
The sample fails the test, if any of the 10 tablets
cracked, cleaved, or broken is present. If the weight loss
is more than 1.0%, the test is repeated for twice and the
mean of three tests is calculated. The mean not more than
1.0% is considered acceptable.
Please note that for Effervescent tablets and chewable
tablets the friability limits may differ.

Answer / 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.
