Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Mass fraction 99.6% > 125 µm, 0.3% > 90 µm < 125 µm; No guideline followed; Foell & Dilts (2012)
Additional information
The granulometry of the test material was assessed in a non-GLP study conducted to sound scientific principles with a sufficient level of detail to assess the quality of the presented results. The test material was passed through a series of sieve screens and the resulting mass fractions were determined. The test material was sieved through a 125 μm opening and a 90 μm opening sieve. Under the conditions of the test 99.6% of the sample was retained on the 125 µm screen, 0.3% of the sample was retained on the 90 µm screen and 0 % of the sample was collected below the 90 µm screen. Under the conditions of the test, the majority of the sample (99.6%) was determined to be > 125 µm. In accordance with EN481 (1993) the test material does not meet the definition of inhalable. The study was assigned a reliability score of 2 in line with the principles for assessing data quality as outlined in Klimisch (1997),
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.
