Conclusions:

The relative density of the test substance is 1.442 g/cm3 at 20ºC.

Executive summary:

The density determination of the test substance, using the Gay-Lussac pycnometer in accordance with EEC 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 1.442 g/cm3, and the average calculated relative density at 20°C temperature was 1.442.
