Principle of method
Pour Density: It is the ratio
of known weight of test item
and its volume in graduated
Tap Density: It is the
difference between the
volume of test item
measured before & after
tapping in the graduated
Test temperature (°C)
pressure (in hPa)

Volume of test item
without tapping (V)
after tapping ( V1)
After 10 tapping
*ρat=density of air at 27°C and 760 mm
Hg pressure= 0.001168 g/cm³
Pour Density of test Item
Tap density of test Item
The density of test chemical was
determined following OECD Guideline 109 (Density of Liquids and Solids)
and according to the method recommended in the International
Pharmacopoeia, fourth Edition, 2014 . The mean pour density and tapped
density of the test chemical was determined to be 0.4882 g/cm³ and
0.7419 g/cm³ at 25°C and 964.65 hPa.
