Reference
Results
Two test series of 3 measurements each were performed with the test item.
Test series 1:
D10: 3.6 μm
D50: 14.0 μm (Median diameter)
D90: 55.6 μm
Test series 2:
D10: 3.6 μm
D50: 14.3 μm (Median diameter)
D90: 55.1 μm
Average
D10: 3.6 μm
D50: 14.1 μm (Median diameter)
D90: 55.4 μm
Final Results
The test item has a median particle size D50 = 14 μm, which was determined by laser diffraction measurement.
Description of key information
Median particle size (D50) = 14.1 μm (OECD Guideline 110, laser diffraction method)
Additional information
The particle size distribution of test substance is also characterized by the following parameters:
D10 = 3.6 μm
D90 = 55.4 μm
