Fertilizers — Determination of bulk density (tapped)
Description
This document specifies two methods for the determination of the bulk density (tapped) of solid fertilizers:
- the machine-tapping method (method 1);
- the hand-tapping method (method 2).
These methods are applicable to dry fertilizers only.
Neither method is suitable for materials which contain a large proportion of particles exceeding 5 mm in diameter.
Method 2 is applicable only to spherical granules and to prills. It is not applicable to sharp-edged grains.
NOTE Because of the differences in tapping technique, the two methods will not necessarily give the same value for the bulk density (tapped).
