- Conclusions:
- The relative density of the test item is 1.411.
- 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 1.411 g/ml, and the average calculated relative density at 20°C temperature was 1.411.
