Final results
The test item has a coarse fraction > 2000 µm of 66.3 wt.-%. The fine
fraction has a median particle size of D50 = 555.7 µm, which was
determined by laser diffraction measurement according to OECD 110 (1981).
Applicant's summary and conclusion
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.
