Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A study conducted on the reference substance (White & Mullee, 2007) concluded that too few particles were of a size less than 10.0 µm to allow accurate assessment of mass median aerodynamic diameter.
Particle size data acquired for the test material are shown as follows:
Proportion of test material having an inhalable particle size less than 100 µm = 26.1% (Sieve method)
Proportion of test material having a thoracic particle size less than 10.0 µm = 5.46% (Cascade Impactor)
Proportion of test material having a respirable particle size less than 5.5 µm = 0.906% (Cascade Impactor)
Additional information
The method used is designed to comply with that given in 'Particle Size Distribution, Fibre Length and Diameter Distribution', June 1996 European Commission technical guidance document, which satisfies the requirements of OECD Guideline 110.

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.
