Conclusions:
The average calculated density of the tested material at 20°C temperature was 1.305 g/ml.
Executive summary:

Determination of density was carried out in accordance with OECD 109 Guideline and EU method A.3, with GLP. The density determination of the tested material was performed using the Gay-Lussac pycnometer. The average measured density of the tested material at 20°C was 1.305 g/mL. The relative density of the tested material at 20°C is 1.305.

Description of key information

Key study: Test method according to OECD guideline 109 and EU method A.3. GLP study. The average calculated density of the tested material at 20°C temperature was 1.305 g/ml.

Key value for chemical safety assessment

Relative density at 20C:
1.305

Additional information

Key study: The density determination of the tested material using the Gay-Lussac pycnometer was based on the calculated difference in weight between the full and empty pycnometer and its volume. The average measured density of the tested material at 20°C was 1.305 g/mL. The relative density of the tested material at 20°C is 1.305.
