What affect the bulk density accroding to USP 616 Bulk Density and Tapped Density of Powders using a tap density tester?

The bulking properties of a powder are dependent upon the preparation,treatment,and storage of the sample,i.e.how it was handled.The slightest disturbance of the powder bed may result in a changed bulk density.
