- Key result
- Type:
- relative density
- Density:
- 1.22 other: dimensionless
- Temp.:
- 20.3 °C
- Conclusions:
- The relative density at ambient temperature (compared to water at 4 °C) was determined to be 1.22 (20.3 °C).
- Executive summary:
A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. The density was determined in two test series with three determinations each. Using the air comparison pycnometer method the density was determined to be 1.2181 g/cm3 at 20.3 °C and the relative density 1.22 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 (20.3 °C).

Mean density ρPR for the two test series: 1.2181 g/cm3. The relative density at ambient temperature (compared to water at 4 °C) was determined to be 1.22 (20.3 °C).
Description of key information
The relative density at ambient temperature (compared to water at 4 °C) was determined to be 1.22 (20.3 °C).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.22
Additional information
A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item (reference 4.4-1). The density was determined in two test series with three determinations each. Using the air comparison pycnometer method the density was determined to be 1.2181 g/cm3 at 20.3 °C and the relative density 1.22 with respect to water at 4 °C, respectively.
