Reference
Results:
The test item consisted of transparent particles which appeared
irregular formed.
The test item was sieved with a mesh size of 1000 pm. 98.7 % (w/w) of
the test item passed the sieve and only this fraction was measured with
laser diffraction.
The particles were introduced to the analyser beam by the dry powder
feeder by direct spraying through the measurement area. The powder was
loosened by an integrated vibrator. The particles were dispersed and fed
to the optical system by pressurized dry air (1.5 bar). After passing
the analyser beam the sample was collected in a vacuum cleaner. After
adjusting the laser, measuring the background and adjusting the correct
particle concentration (obscuration) the measurement was started. The
control software automatically performed three measurements. The average
of these three measurements was given as result. Two test series of
three measurements each were performed. The measurement time was 8 s.
Individual results:
D50: 9.77 µm (1st test series), 9.82 µm (2nd test series)
D10: 2.64 µm (1st test series), 2.67 µm (2nd test series)
D90: 28.26 µm (1st test series, 27.95 µm (2nd test series)

EPA OCSPP 830.7520):
D50: 9.8 µm
D10: 2.7 µm
D90: 28.1 µm
