- Key result
- Type:
- relative density
- Density:
- 1.41 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- Under the conditions of this study the density of the test material was 1.4124 g/cm^3 at 20 °C.
- Executive summary:
The relative density of the test material was investigated in accordance with the standardised guidelines EU Method A. 3, OECD 109 and EPA OPPTS 830.7300 in compliace with GLP, using the pycnometer method.
Using this method, a known weight of the test material was placed in the sample cell and its volume determined by the density tester. The density of the test material was calculated from its weight and volume. The final density is the mean average of the five independent tests performed.
Under the conditions of this study the density of the test material was 1.4124 g/cm^3 at 20 °C. The relative density was determined to be 1.41.

Additional information
The relative density of the test material was investigated in accordance with the standardised guidelines EU Method A. 3, OECD 109 and EPA OPPTS 830.7300 in compliace with GLP, using the pycnometer method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Using this method, a known weight of the test material was placed in the sample cell and its volume determined by the density tester. The density of the test material was calculated from its weight and volume. The final density is the mean average of the five independent tests performed.
Under the conditions of this study the density of the test material was 1.4124 g/cm^3 at 20 °C. The relative density was determined to be 1.41.
