- Percentile:
- D50
- Mean:
- >= 162 µm
- Remarks on result:
- other: Unmilled material - standard deviation = 126 microns(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- Percentile:
- D10
- Mean:
- >= 75 µm
- St. dev.:
- 126
- Percentile:

Applicant's summary and conclusion
- Conclusions:
- For unmilled material, mean particle size = 193 microns, median particle size = 163 microns, 80% of distribution (D10 to D90) falls within 75 to 356 microns.
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.
