Results
Measurement chamber with a volume of Vc= 7.8961 cm3 and
an expansion chamber with a volume of Vr= 6.0848 cm3 were
used. Two test series with different weights were done at a temperature
of 20 °C. Results are show in Tables 1 and 2.

Mean density ρPR for the two test series is 2.20 g/cm3. Relative density (compared to water at 4 °C) is:
D4R= 2.20 ± 0.01
Description of key information
Relative density: 2.20 at 20 °C (OECD 109, air comparison pycnometer).
Key value for chemical safety assessment
- Relative density at 20C:
- 2.2
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.
