The friabilty tester measures how much weight does the drug loses after a certain number of drops. Tablets are dropped from 6 inches at 25 rpm for 100 times. As for drugs with a film coating, they are dropped for 500 times.
If the tablet mass is less than 650mg, only tablets which weight 6.5g should be selected for the friability test. For tablets which are heavier than 650mg, 10 tablets should be randomly selected for this test.
If the weight loss is larger than 1%, the drug may require reformulation. The pressure used to form the drug may need to be increased ad beveled edge tooling may be used to produce them.

Why is the friability tester set at 100 revolutions?
The friability tester is typically set at 100 revolutions as this is the standard requirement in pharmacopeial guidelines for testing the friability of tablets. This number of revolutions is commonly used to simulate the handling and transportation stress that tablets may undergo during manufacturing and distribution.
How friability is measured?
Friability is typically measured using a friability tester, which consists of a rotating drum that tumbles a sample of tablets or granules for a specified time. After tumbling, the sample is weighed to determine the weight loss due to abrasion and breakage, which is expressed as a percentage. This percentage indicates the friability of the tablets or granules.
What is the formula to calculate friability?
friability F=I-F.100/I where I =Iinitial weight of tablets , F = weight after friability. Normal limit less than 1%.

What is sands friability?
Sands friability refers to how easily sand can be broken down into smaller particles or dust when subject to pressure or friction. Sands with lower friability will be more resistant to breaking down, while sands with higher friability will be more prone to fragmentation. This property can impact the handling, transportation, and stability of sand materials in various applications.
