- density
- Density:
- 1.36 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test substance was 1.360 at 20ºC.
- Executive summary:
The determination of the relative density of the test substance was carried out through a pycnometer method, at 20ºC, measuring the mass of the test item in a known volume. The procedure was in accordance with the EU Method A.3 (CIPAC MT 3.2.1) and followed the Principles of GLP. The average measured absolute density of the tested material at 20ºC temperature was 1.360 g/mL and the average calculated relative density of the tested material at 20ºC was 1.360.
