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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two independent measurements at 21.0°C (assay No. 1) and 21.2°C (assay No. 2) were done. Runs 1, 2, 3 and 4 of assay No. 1 were not taken into account because they did not comply with the quality criterion, also runs 1, 2 and 3 of assay No. 2 were not taken into account because they did not comply with the quality criterion.
The two assays resulted in relative densities of 5.730 ± 0.005 and 5.681 ± 0.005, respectively. The mean relative density was thus 5.706 ± 0.027 at 21.1°C.
Reference volume (VA) was 79.444 cm³.
Volume of sample cell holder (VC) was 27.678 cm³.
Test item sample weight was 8.4001 g and 8.1090 g in assay No. 1 and 2, respectively.
The measurements are described in the table in the next section.
Description of key information
Based on the guideline study (Klimisch 1, Demangel, 2017) the mean relative density of the test item is 5.706 ± 0.027 at 21.1°C.
Key value for chemical safety assessment
- Relative density at 20C:
- 5.706
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.
