- Conclusions:
- The average calculated relative density of the tested material at 20°C temperature was 1.622.
- 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 absolute density of the tested material at 20°C was 1.622 g/mL. The average calculated relative density of the tested material at 20°C was 1.622.

Description of key information
Key study: Test method according to OECD 109 and EU method A.3. GLP study. The average calculated relative density of the tested material at 20°C temperature was 1.622.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.622
Additional information
Key study: The density determination of the tested material, using Gay-Lussac pycnometer, was based on the calculated difference in weight between the full and empty pycnometer and its volume. The average measured absolute density of the tested material at 20°C was 1.622 g/mL. The average calculated relative density of the tested material at 20°C was 1.622.
