- Key result
- Type:
- relative density
- Density:
- 1.02 other: dimensionless
- Temp.:
- 19.8 °C
- Conclusions:
- The relative density of the test item was determined to be 1.02 at 19.8 ± 0.5 °C (absolute density: 1.02E+03 kg/m3).
- Executive summary:
The determination of density was carried out using a gas comparison pycnometer and a procedure designed to be compatible with OECD TG 109 and in compliance with GLP. The density measured at 19.8 ± 0.5 °C was 1.02 (absolute density: 1.02E+03 kg/m3).

Mean reference cell volume : 90.907 cm3
Mean sample cell volume : 149.077 cm3
As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3 and 149.225 ± 1.0 cm3 for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.
