Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Relative density and density 0.947 and 947 kg/m³, respectively, at 20.0 ± 0.5 °C, OECD 109, EU Method A.3, Fox (2015a)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.947
Additional information
The density of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guidelines OECD 109 and EU Method A.3. All methodology and results were reported in full. The study was therefore assigned a reliability score of 1 in accordance with the principles for assessing data quality as described by Klimisch et al. (1997).
The determination was carried out with a gas comparison pycnometer. Following calibration of the system using a stainless steel calibration sphere (carried out in triplicate), a glass vessel was placed in the sample cell of the pycnometer. The pressure readings were recorded after pressurising the reference cell of determined volume and then after adding the sample cell of determined volume to the system.
The test material was transferred to the vessel until approximately half full and then equilibrated to 20.0 ± 0.5 °C prior to being weighed. The vessel containing test material was then placed in the sample cell and pressure readings were recorded after pressurising the reference cell and then after adding the sample cell to the system. Triplicate measurements were taken for two independent determinations.
The density of the test material has been determined to be 947 kg/m³ at 20.0 ± 0.5 °C and the relative density to be 0.947.
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.
