- Type:
- density
- Density:
- 910 kg/m³
- Temp.:
- 21 °C
- Remarks on result:
- other: Temperature ± 0.5 °C
- Conclusions:
- Lighter than water, relative density 0.910 at 21.0 ± 0.5 °C
- Executive summary:
The density of the test item was determined in a GLP-compliant study using a gas comparison pycnometer according to the EU A.3 (2008) and OECD TG 109 (1995) protocol. The experiment is deemed valid, conclusive and thus suitable for assessment without restrictions.
The relative density was measured to be 0.910 at 21.0 ± 0.5 °C, which corresponds to a density of 910 kg/m³, which indicates that the test item is lighter than water.

Description of key information
Lighter than water (EU Method A.3)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.91
Additional information
The density was determined in a GLP-compliant study (Fox & White 2012, Harlan Report no. 41103263) using a gas comparison pycnometer according to the EU A.3 (2008) and OECD TG 109 (1995) protocol. The experiment is deemed valid, conclusive and thus suitable for assessment without restrictions.
The relative density was measured to be 0.910 at 21.0 ± 0.5 °C, which corresponds to a density of 910 kg/m³ and indicates that the submission item is lighter than water.
