- Type:
- relative density
- Density:
- 1.266 other: dimensionless
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 1 266 kg/m³
- Temp.:
- 20 °C
- Conclusions:
- Under the conditions of the study the relative density of the test material was 1.266 and the density was 1266 kg/m³ at 20°C.
- Executive summary:
The relative density of the test material was assessed in accordance with the standardised guidelines OECD 109 and EU Method A.3 under GLP conditions.
The density was calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests were run at a constant temperature, preferably 20°C, and at least two measurements were performed.
Under the conditions of the study the relative density of the test material was 1.266 and the density was 1266 kg/m³ at 20°C.

Additional information
The relative density of the test material was assessed in accordance with the standardised guidelines OECD 109 and EU Method A.3 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The density was calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests were run at a constant temperature, preferably 20°C, and at least two measurements were performed.
Under the conditions of the study the relative density of the test material was 1.266 and the density was 1266 kg/m³ at 20°C.
