Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Mean reference cell volume: 90.895 mL
Mean sample cell volume: 149.135 mL
As the reference cell and sample cell volume were within the defined tolerance: 90.953 ± 1.0 mL and 149.225 ± 1.0 mL for the reference and sample cell, respectively. The gas comparison pycnometer was therefore considered acceptable for use.

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.
