Description of key information
Under the conditions of this study the average size of the particles was determined to be 28.31 µm.
Additional information
The key study was assigned a reliability score of 2 in accordance with the criteria for assessing data quality defined in Klimisch (1997).
The granulometric content of the test material was evaluated using a laser diffraction particle size analyser, Microtrac S3000.
A sample of the test material was dispersed into de-ionised water and processed ultrasonically; the suspension was then re-circulated and settled by three laser beams. The laser beams were dispersed by the particles and collected with multi-elemental detectors for analysis.
Under the conditions of this study the average size of the particles was determined to be 28.31 µm.
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.
