Description of key information
The L10 D (v, 0.1) was determined to be 2.5 µm, the MMAD L50 D (v, 0.5) was determined to be 17.0 µm and the L90 D (v, 0.9) was determined to be 78.4 µm by Laser Diffraction method according to the national standard method (CIPAC MT 187) .
Additional information
Based on the result of the median particle size L50(D(v, 0.5) (50% of particle volume or particle mass with lower particle diameter) of 17 µm the dustiness category of 'medium dusty form' of solids was selected in the Chesar tool in accordance with the modelECETOC TRA Worker 3.0 tool and the ECETOC Technical Report No. 114 considering a worst case approach.
