- relative density
- Density:
- 1.382 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The average measured absolute density of the test item at 20°C is 1.382 g/ml, and the average calculated relative density at 20°C is 1.382.
- Executive summary:
The density determination of the test item, using the Gay-Lussac pycnometer in accordance with EU Method A3 (CIPAC MT 3.2.1) was based in measuring the mass of the substance occupying a unit volume at 20˚C (GLP study). The average measured absolute density at 20°C was 1.382 g/ml, and the average calculated relative density at 20°C temperature was 1.382.

Additional information
The density determination of the test item, using the Gay-Lussac
pycnometer in accordance with EU Method A3 (CIPAC MT 3.2.1) was based in
measuring the mass of the substance occupying a unit volume at 20˚C (GLP
study). The average measured absolute density of the test item at 20°C
was 1.382 g/ml, and the average calculated relative density at 20°C
temperature was 1.382.
