Conclusions:
Under the conditions of this study, the density of the test material at 20 °C was 1187 Kg/m³. The relative density was 1.187.
Executive summary:

The density and relative density of the test material were determined in accordance with the standardised guidelines OECD 109 and EU Method A.3 under GLP conditions using a pycnometer.

The density is calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests are run at a constant temperature, preferably 20 °C, and at least two measurements are performed.

Under the conditions of this study, the density of the test material at 20 °C was 1187 Kg/m³. The relative density was 1.187.

Additional information

The density and relative density of the test material were determined in accordance with the standardised guidelines OECD 109 and EU Method A.3 under GLP conditions using a pycnometer. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

The density is calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests are run at a constant temperature, preferably 20 °C, and at least two measurements are performed.

Under the conditions of this study, the density of the test material at 20 °C was 1187 Kg/m³. The relative density was 1.187.
