RS ISO 5311: 1992
Fertilizers — Determination of bulk density (tapped)
Abstract

This International Standard 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.
If the fertilizer has absorbed moisture during transport
or storage, it is necessary to dry it in an environmental
chamber, with constant low humidity,
Prior to the determination.
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. lt is not applicable to sharp-edged
grains.
NOTE 1 Because of the differentes in tapping technique,
the two methods will not necessarily give the same
value for the bulk density (tapped).
