Reference
Results
Measurements of the test item were made in each of two test series:
Test series 1
D10: 49.6 µm
D50: 163.3 µm (Median diameter)
D90: 367.9 µm
Test series 2
D10: 50.6 µm
D50: 166.9 µm (Median diameter)
D90: 370.4 µm
Average
D10: 50.1 µm
D50: 165.1 µm (Median diameter)
D90: 369.2 µm
Final results
The test item has a median particle size D50= 165 µm, which was determined by laser diffraction measurement.
Description of key information
Particle size distribution: 50.1 µm (D10), 165.1 µm (D50) and 369.2 µm (D90), (OECD 110, laser diffraction)
