- Key result
- Percentile:
- D50
- Mean:
- 44.1 µm
- St. dev.:
- 0.607
- Key result
- Percentile:
- D90
- Mean:
- 170 µm
- St. dev.:

- Conclusions:
- The particle size distribution of the test item was determined by means of Laser Diffraction Analysis using the medium volume (wet) module (MVM).
The D50 of the test item was determined to be 44.1 μm, the D10 was 10.7 μm and the D90 was 170 μm. The MMAD of the test item, for the relative density and the mean d50, was calculated to be 52.9 μm. Volume of sample < 10.00 μm was determined to be 8.77% (< 9.86 μm). - Executive summary:
The particle size distribution of the test item was determined by means of Laser Diffraction Analysis using the medium volume (wet) module (MVM).
The D50 of the test item was determined to be 44.1 μm, the D10 was 10.7 μm and the D90 was 170 μm. The MMAD of the test item, for the relative density and the mean d50, was calculated to be 52.9 μm. Volume of sample < 10.00 μm was determined to be 8.77% (< 9.86 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.
