D90 = 301.4 ± 17.57.
Reference
The 10% particle size of the substance was 1.495, 1.621 and 1.801µm for replicates R1, R2 and R3, rispectively.
The 50% particle size of the substance was 94.58, 106.4 and 116.2µm for replicates R1, R2 and R3, rispectively.
The 90% particle size of the substance was 281.1, 310.6 and 312.4µm for replicates R1, R2 and R3, rispectively.
Description of key information
The mean particle sizes (µm) and Standerd Deviation of the substance were:
D10 = 1.639 +- 0.15;
D50 = 105.7 +- 10.83;
D90 = 301.4 +- 17.57.
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.
