Results
Two test series of 3 measurements each were performed with the test item.
The test item shows a mono-modal particle size distribution.
The percentages of the cumulative particle size distribution for specific particle sizes:
Test series 1 | ||
D10 | 3.7 µm | Standard deviation: 0.08 µm |
D50 | 10.0 µm (Median diameter) | Standard deviation: 0.13 µm |
D90 | 18.4µm | Standard deviation: 0.19 µm |
Test series 2 | ||
D10 | 3.6 µm | Standard deviation: 0.01 µm |
D50 | 9.8 µm (Median diameter) | Standard deviation: 0.03 µm |
D90 | 17.9 µm | Standard deviation: 0.04 µm |
Average | ||
D10 | 3.7 µm | Standard deviation: 0.06 µm |
D50 | 9.9 µm (Median diameter) | Standard deviation: 0.12 µm |
D90 | 18.2 µm | Standard deviation: 0.21 µm |
Cumulative passing of specific particle sizes:
Particle size / µm | Passing / % | Passing / % | Passing / % |
1 | 0.14 | 0.15 | 0.15 |
2 | 3.48 | 3.65 | 3.57 |
4 | 11.13 | 11.66 | 11.40 |
10 | 50.02 | 51.78 | 50.90 |
20 | 93.49 | 94.28 | 93.89 |
25 | 99.02 | 99.28 | 99.15 |
50 | 100.00 | 100.00 | 100.00 |
Applicant's summary and conclusion
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.
