| Mean *) | 49.1 | 99.6 | 176 | 79.9 | 107 |
*) Using all single measuring points from the distributions 1 and 2, a new distribution was calculated, giving the mean values for each parameter.
<100 µm: 50.3%; <10 µm: 0.1% <4µm: 0.0%
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.
