- Conclusions:
- A gas comparison pycnometer was used for the determination of the density and relative density of the substance in accordance with OECD 109 (1995), EU Method A.3 and GLP. The density of the test substance at 19.8ºC was 1.093 g/cm3. The relative density was 1.093.
Reference
- Calibration
A mean value of 56.4142 +/- 0.0028 cm^3 was obtained, which was considered to be acceptable.
