To calculate absolute density the following equation were used:

ρ = ρw– [ρa· (m – m0)/(m1– m0)] + ρa

To calculate relative density the following equation was used:

ρ204 = ρt / ρ4water

Conclusions:
The average calculated relative density of the tested material at 20°C temperature was 1.270.
Executive summary:

Determination of relative density was carried out in accordance with the EU A.3 method, with GLP. The density determination of the tested material, using the Gay-Lussac pycnometer. The average measured absolute density of the tested material at 20°C temperature was 1.270 g/mL. The average calculated relative density of the tested material at 20°C temperature was 1.270.
