Reference
Results
Before the measurements the agglomerates of the test item were to crush carefully. Two test series of 3 measurements each were performed with the test item.
Test series 1:
D10: 25.9 μm
D50: 136.4 μm (Median diameter)
D90: 361.7 μm
Test series 2:
D10: 27.9 μm
D50: 139.5 μm (Median diameter)
D90: 362.5 μm
Average
D10: 26.9 μm
D50: 138.0 μm (Median diameter)
D90: 362.1 μm
Final Results
The test item has a median particle size of D50= 138.0 μm, which was determined by laser diffraction measurement.
Description of key information
Median particle size (D50) = 138.0 μm (ISO 13320, laser diffraction method)
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.
