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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
The density of the materials was determined with the Accupyc 1330, manufactured by Micromeritics in 1998. The pycnometer determines density and volume of solids by measuring the pressure change of helium gas in a calibrated volume. Analysis measures sample volume, from which density can be derived when sample weight is known. The measurement is accurate within ±0.03% and the optional sample range is 1-100 cm3. Reproducibility is guaranteed to within ±0.02% of the nominal full-scale volume on clean, dry, thermally equilibrated samples. This measurement is congruent with EU method A.3 (relative density). |

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.
