Note: As the difference between results was less than 0.03 g/ml; hence two trials were enough.

Conclusions:
The relative density at 20ºC temperature was 0.894.
Executive summary:

Determination of density was carried out in accordance with OECD 109 Guideline, with GLP. The density determination of the tested material was performed using the Gay-Lussac Pycnometer. Two samples were tested. The average measured density of the tested material at 20°C was 0.894 g/mL. The relative density of the tested material at 20°C was calculated to be 0.894.
