- Percentile:
- D90
- Mean:
- 103.82 µm
- St. dev.:
- 1.15
- Remarks on result:
- other: Mean of two measurements
- Conclusions:
- The L10 D (v, 0.1) was determined to be 5.83 µm, the L50 D (v, 0.5) was determined to be 23.21 µm and the L90 D (v, 0.9) was determined to be 103.82 µm.
- Executive summary:
The particle size distribution of a dried sample was determined using the laser diffraction method with dry dispersion following CIPAC MT 187. The dispersing energy was adjusted to 4.0 bar. Two measurements have been performed. The L10D (v, 0.1) was determined to be 5.83 µm, the L50D (v, 0.5) was determined to be 23.21 µm and the L90D (v, 0.9) was determined to be 103.82 µm.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
