- primary particle
- Type of distribution:
- volumetric distribution
- Mass median aerodynamic diameter:
- 80.3 µm
- Key result
- Percentile:
- D90
- Mean:
- 165.2 µm
- Remarks on result:
- other: Standard deviation not measured
- Key result
- Percentile:
- D10
- Mean:
- 32.7 µm
- Remarks on result:
- other: standard deviation not measured
- Conclusions:
- The results of determination of particle size distibution of the test substance are:
Median: 80.3 µm
Diameter on cumulative 90% (d90): 165.2 µm
Diameter on cumulative 10% (d91): 32.7 µm
Reference
Extended uncertainty of determination of the median is 10%.
Extended uncertainty was calculated by using coefficient 2 (for normal distribution agrees with probability of coverage about 95%).
Description of key information
The results of determination of particle size distibution of the test substance are:
Median: 80.3 µm
Diameter on cumultive 90% (d90): 165.2 µm
Diameter on cumultive 10% (d91): 32.7 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.
