- Conclusions:
- The relative density of the test item was found to be 1.260.
- Executive summary:
The density of the test item was determined in accordance with EU method A3 (CIPAC MT 3.2.1), under GLP conditions, using the Gay-Lussac pycnometer in accordance based in measuring the mass of the substance occupying a unit volume at 20˚C. The average measured absolute density at 20°C was 1.260 g/cm³ , and the average calculated relative density at 20°C temperature was 1.260.
Reference
As the difference between results was less than 0.03 g/ml; two trials were enough.

Additional information
The density determination of the test item was determined in accordance with EU method A3 (CIPAC MT 3.2.1), under GLP conditions, using the Gay-Lussac pycnometer in accordance based in measuring the mass of the substance occupying a unit volume at 20˚C. The average measured absolute density at 20°C was 1.260 g/cm³ , and the average calculated relative density at 20°C temperature was 1.260.
