Method

Test methods: Pour density and tapped density of powders recommended in

The International

Pharmacopoeia, Fourth

Edition, 2014

 

 

Principle of method

Pour Density:It is the ratio of known weight of test item and its volume in graduated glass cylinder.

Tap Density:It is the

difference between the

volume of test item

measured before & after

tapping in the graduated

glass cylinder.
