Conclusions:
Under the conditions of this study, the density of the test material at 20 ºC was 0.852 g/cm^3 (0.852 x 10^3 kg/m^3). The relative density was 0.852.
Executive summary:

The density and relative density of the test material was investigated in accordance with the standardised guidelines OECD 109, EU Method A.3. and OPPTS 830.7300, under GLP conditions using a pycnometer.

Under the conditions of this study, the density of the test material at 20 ºC was 0.852 g/cm^3 (0.852 x 10^3 kg/m^3). The relative density was 0.852.

Additional information

The density and relative density of the test material was investigated in accordance with the standardised guidelines OECD 109, EU Method A.3. and OPPTS 830.7300, 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).

Under the conditions of this study, the density of the test material at 20 ºC was 0.852 g/cm^3 (0.852 x 10^3 kg/m^3). The relative density was 0.852.
