Description of key information
Two samples were tested, 09TT11160 and sample 09TT11161, with respectively D50 = 1679 µm and D50 = 569 µm. Nevertheless the result of the test should be used with caution since the tested samples were crushed prior to testing.
Testing demonstrates that the UVCB does NOT contain inhalable particles (particle size less than 100 µm), which are capable of entering the respiratory tract under realistic breathing conditions.
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.
