- Density:
- 1.42 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The relative density at ambient temperature (compared to water at 4°C) was determined to be 1.42.
- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 determine the relative density of the test item. The density was determined in six independent determinations. Using the pycnometer method the density was determined to be 1.4182 g/cm3 at 20 °C and the relative density 1.42 ± 0.01 with respect to water at 4 °C respectively.
Reference
A 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 performed at ambient temperature (20.0 °C).

Description of key information
The relative density at ambient temperature (compared to water at 4°C) was determined to be 1.42 (reference 4.4 -1).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.42
Additional information
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 determine the relative density of the test item (reference 4.4 -1). The density was determined in six independent determinations. Using the pycnometer method the density was determined to be 1.4182 g/cm3 at 20 °C and the relative density 1.42 ± 0.01with respect to water at 4 °C respectively.
