- Type of method:
- air comparison pycnometer (for solids)
- Type:
- relative density
- Density:
- 0.893 other: relative density has no dimension
- Temp.:
- 21.3 °C
- Conclusions:
- The relative density at an ambient temperature of 21.3 °C (compared to water at 4°C) is 0.893.
- Executive summary:
The relative density of the sample was tested according to EU Method A.3 and OECD Guideline 109 in a non-GLP study with a gas comparison pycnometer. The relative density at an ambient temperature of 21.3 °C (compared to water at 4°C) is 0.893.
Reference
Two test series with different weights were performed at ambient temperature (21.3 °C).

Description of key information
The relative density of the sample was tested according to EU Method A.3 and OECD Guideline 109 in a non-GLP study with a gas comparison pycnometer. The relative density at an ambient temperature of 21.3 °C (compared to water at 4°C) is 0.893.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.893
Additional information
Key value for the risk assessment was not measured at an ambient temperature of 20 °C. Ambient temperature was determined to be 22.8 °C. Nevertheless this difference can be disregarded due to only minor changes in the respective key value for chemical safety assessment.
