- Specific details on test material used for the study:
- Identity: FAT 40812/A
Batch: WP 8/03
Appearance: Solid, dark red-brownish powder
Expiration date: 23 April 2010
Storage: At room temperature at about 20 °C - Mass median aerodynamic diameter:
- ca. 41.8 µm
- Percentile:
- D10
- Mean:
- < 12.1 µm
- St. dev.:
- 1.028
- Percentile:
- D50
- Mean:
- < 41.8 µm
- St. dev.:
- 3.151
- Percentile:
- D90
- Mean:
- < 101 µm
- St. dev.:
- 8.175
- Conclusions:
- The mass median (aerodynamic) diameter of the test substance is 41.8 µm. The particle size distribution was found to range from approximately 0.3 µm to 200 µm.
- Executive summary:
In a GLP-compliant study, using the laser scattering/diffraction method, the mass median diameter of the test substance was determined. Based on the findings of this study, the mass median (aerodynamic) diameter (MMAD) was determined to be 41.8 µm. The particle size distribution was found to range from approximately 0.3 µm to 200 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.
