Reference
Given standard deviation is based on the general experience with the method. The estimated values are typical standard deviations:
D10: 4 % of D10 (minimum value 0.05 µm)
D50: 13 % of D50 (minimum value 0.1 µm)
D90: 29 % of D90 - D50
Description of key information
D10: 10 µm
D50: 117 µm
D90: 537 µm
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.
