Reference
Results
Three measurements of the test item were made in each of two test series
Test series 1
D10: 24.7 µm
D50: 160.0 µm (Median diameter)
D90: 371.6 µm
Test series 2
D10: 28.8 µm
D50: 162.7 µm (Median diameter)
D90: 373.1 µm
Average
D10: 26.7 µm
D50: 161.4 µm (Median diameter)
D90: 372.3 µm
Final results
The test item has a median particle size D50 = 161 µm, which was determined by laser diffraction measurement.
Description of key information
Particle size distribution: 26.7 µm (D10), 161.4 µm (D50) and 372.3 µm (D90), (OECD 110, laser diffraction).
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.
