Reference
The mean dustiness was determined to be 29.0% D (dust content) < 50 µm based on 2 determinations.
Description of key information
Based on an experimental study (De Ryckel, 2017) according to the CIPAC 187 (laser diffraction) method, assigned reliable with restrictions (K2), the mean particle size is 128.317 µm (Dv,50). The Dv,10 and Dv,90 values were determined to be 14.387 µm and 405.599 µm, respectively.
Additional information
The Dv,10; Dv,50 and Dv,90 values were determined to be 14.387 µm, 128.317 µm and 405.599 µm, respectively
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
