D4R = 1.45 (20.0 °C)
Reference
Results:
A measurement chamber with a volume of Vc= 7.8961 cm3and an expansion chamber with a volume of Vr= 6.0848 cm3were used.
Two test series with different weights were performed at ambient temperature (20.0 °C). For results see Table1 and Table2.

Description of key information
The density of the test item was determined according to the European Commission Regulation (EC) No. 440/2008, Method, A.3. Density of liquids and solids: Gas comparison pycnometer and according to the OECD test guideline, OECD 109 Density of liquids and solids.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.45
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
