- Type:
- relative density
- Density:
- 1.429
- Temp.:
- 20 °C
- Conclusions:
- Relative density: 1.429, at 20 °C
- Executive summary:
The density of the test substance was measured using the pycnometer method. The procedure was performed according to the EU Method A.3 and according to the OECD guideline 109. The density was calculated from the difference in weight between the full and empty pycnometer and its known volume. The relative density was calculated as a ratio of densities of the substance at 20 °C and water at 4 °C.
Conclusion
Relative density: 1.429, at 20 °C
