Description of key information
62.4 % of the test item consists of particles bigger than 1000 µm.
Additional information
The purpose of this study was the determination of the particle size distribution by laser diffraction of the test items. The study was performedaccording to the European Commission Regulation (EC) No. 440/2008and under consideration of thefollowingguidelines OECD 110 (1981):ParticleSize Distribution, CIPACMT 187: Particle Size Analysis by Laser Diffraction,
ISO13320 -1: Particle Size Analysis - Laser Diffraction Methods.62.4 % of the test item consists of particles bigger than 1000 µm.
The median particle size L50 of the test items deduced from the particle size distributions is 292.3 µm.
The particle size L10 of the test items deduced from the particle size distributions is 10.1 µm.
The particle size L90 of the test items deduced from the particle size distributions is 1007.5 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.
