Reference
Results:
The test item consisted of transparent particles which had
different shapes and were partially agglomerated.
Two test series of three measurements each were performed.
The measurement time was 8 s.
Individual results:
D50: 287.57 µm (1st test series), 275.07 µm (2nd test series)
D10: 6.47 µm (1st test series), 6.35 µm (2nd test series)
D90: 904.00 µm (1st test series, 877.02 µm (2nd test series)
The measurements showed maxima at approximately 5 µm and
approximately 500 µm and a shoulder at approximately 100 µm.
