- Executive summary:
The objective of the test was to determine the particle size distribution of a solid test item by test sieving in the most satisfactory conditions.
Type of distribution: particle size distribution. The particules were spread like this: 21.8% between 4 mm and 2.8 mm, 32.1% between 2.8 and 2 mm, 33.8% between 2 and 1.4 mm, and 12.2% under 1.44 mm.

Description of key information
In compliance with Guideline OECD No. 110 (1981) NF ISO 2591-1 (1989); NFX11-507 (1989) a granulometry test was performed to determine the particule size distribution of the solid test item by test sieving in the most satisfactory conditions.
The particule size distribution results are : 21.8% between 2.8 mm and 4 mm, 32.1% between 2 and 2.8 mm, 33.8% between 1.4 and 2 mm, and 12.2% under 1.4 mm.
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.
