EC number: 219-260-3
CAS number: 2397-00-4
DETERMINATION OF TAP DENSITY
Sample mass (W): 57.7 g
Sample volume after dropping (V):
Tap density (D): 0.32 g/ml
N. of sieves: 8
Sample mass (m, calculated): 50.7 g
Sample mass (weighed): 50.92 g
gx:the amount of material
retained by the sieve x
rx: ratio * 100 of the
amount of material retained by the sieve x and sample mass
Rx: the calculated sum of
residues on all the x sieves. Therefore the residue Rx on sieve x and
the residues on all coarser sieves were summed.
Particle size distribution of the test
item was determined according to the CIPAC MT 59 Sieve Analysis, CIPAC
MT 170 Dry Sieve Analysis of Water Dispersible Granules and CIPAC MT 169
Tap Density of Water Dispersible Granules test methods. Machine sieving
test was carried out using the following test sieves 4, 2, 1 mm, 500,
250, 100, 63 and 45 µm.
The particle size distribution of the test
item was found to be in the range of 250 and 2000 µm.
Particle size distribution: 250 - 2000 µm
CIPAC MT 59, CIPAC MT 170 and CIPAC MT 169
