Conclusions:
The relative density of the test item is 1.517.
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 20ºC (GLP study). The average measured absolute density at 20°C was 1.517 g/ml, and the average calculated relative density at 20°C temperature was 1.517.

Description of key information
