Sieve aperture size (µm)
Mass of test material transferred to sieve (g)
Mass of test material passed through sieve (g)
Test material less than sieve aperture size (%)
Definitive test (cascade impactor
Particle size cut points (µm)
Cumulative Mass of Test Material (g)
Cumulative Amount of Test Material (%)
Too few particles were of size less than
10.0 µm to allow accurate assessmnet of mass median aerodynamic diameter.
Particle size data have been acquired
following the OECD Guideline 110 and GLP.
Inhalable particles (< 100 µm): 91.7%
Thoracic particles (< 10 µm): 4.08%
Respirable particles (< 5.5 µm): 0.312%
91.7% < 100 µm4.08% < 10 µm0.312% < 5.5 µm
The particle size distribution
(granulometry) of the substance was determined using sieve and cascade
impactor. The method applied is considered equivalent to OECD Guideline
