The mean dustiness was determined to be 29.0% D (dust content) < 50 µm based on 2 determinations.

Conclusions:
The mean particle size of the substance was determined to be 128.317 µm (Dv,50). The Dv,10 and Dv,90 values were determined to be 14.387 µm and 405.599 µm, respectively.

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
