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.
