If the smallest fraction, that leaves the collecting pan should also be weighted, it must be
appropriately collected. After the sieving process, the individual fractions are transferred on
suitable tared filters (paper filter) and dried in an oven at 80 °C until the weight remains
constant.
NOTICE Used test sieves must be cleaned immediately after the sieving process ( Chapter
"Cleaning of Test Sieves"). Depending on the sample material flash rust can form in the sieve
mesh fabric.
The load diagrams are invalid for the wet sieving. Due to the non-defined quantity of liquid in
the sieve stack, binding statements are not possible for the wet sieving.
Recommended parameters for wet sieving:
Amplitude: 1 mm to 1.2 mm
Interval operation: yes
Time: 5 min
