What is the loss of weight in friability test?
A maximum loss of weight (from a single test or from the mean of the three tests) not greater than 1.0 percent is acceptable for most tablets. If obviously cracked, chipped or broken tablets are present in the sample after tumbling, the sample fails the test.
What is the formula for calculating weight loss during friability test?
The formula for friability test use in tablets: w2= Final weight of tablets or weight after the test.
What is the USP upper weight loss limit for the friability test?
A maximum mean weight loss from the three samples of not more than 1.0% is considered acceptable for most products.
How many tablets are used in friability test?
10 whole tablets
It enables tumbling of tablets at each turn of Drum. (F) Procedure of Friability Apparatus: For tablet with an average weight of 0.65g or less; a sample of whole tablet correspond to 6.5g should be taken. For tablet with an average weight of more than 0.65g; then take sample of 10 whole tablets.
How do you calculate the friability of a tablet?
Test Method: Dedust the tablet carefully and weigh accurately the tablet sample. Place the tablets in the drum. Rotate the drum 100 times with a speed of 25 rpm, remove the tablets, remove any loose dust from the tablets as before, and accurately weigh.
How do you calculate weight variation?
Method:
- Weigh an intact capsule.
- Open the capsule without losing any part of the shell and remove the contents as completely as possible.
- Weigh the shell.
- The weight of the contents is the difference between the weighing.
- Repeat the procedure with a further 19 capsules selected at random.
- Determine the average weight.
What is limit of weight variation in IP and USP?

| More than 80mg or Less than 250mg | ± 7.5% | 130mg to 324mg |
| 250mg or more | ± 5% | More than 324mg |
What is weight variation test?
In the case of pharmaceutical dosage forms, the weight variation test (also referred to as uniformity of dosage units) is a non-destructive test that compares the individual weights of a sample of tablets with the average weight of the selected sample.

What is the uniformity of weight test?
INTRODUCTION THE British Pharmacopaeia 1953 includes a test for the uniformity of weight of tablets which requires, that when the tablets in a sample of 20 are weighed singly, not more than 2 deviate from the average weight by a percentage greater than that specified and no tablet deviates by more than double that …
