- Conclusions:
- Under the conditions of this study, the density of the test material has been determined to be 1.03 x 10^3 kg/m^3 at 20.0 ± 0.5 °C; relative density of 1.03.
- Executive summary:
The density of the test material was investigated in accordance with the standardised guidelines OECD 109 and EU Method A.3, under GLP conditions.
As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm^3 and 149.225 ± 1.0 cm^3 for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.
Duplicate determinations were performed to ensure a reproducibility of less than ± 20 kg/m^3 was obtained.
Under the conditions of this study, the density of the test material has been determined to be 1.03 x 10^3 kg/m^3 at 20.0 ± 0.5 °C; relative density of 1.03.

Additional information
The density of the test material was investigated 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).
As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm^3 and 149.225 ± 1.0 cm^3 for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.
Duplicate determinations were performed to ensure a reproducibility of less than ± 20 kg/m^3 was obtained.
Under the conditions of this study, the density of the test material has been determined to be 1.03 x 10^3 kg/m^3 at 20.0 ± 0.5 °C; relative density of 1.03.
