- TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: the test substance was phlegmatized (15 mass% water addition) for the time of transportation. Before the study performance, the sample was dried at room temperature under vacuum conditions until a constant mass was obtained. - Key result

- Conclusions:
- The relative density of the tested material was determned to be 1.5350 at 20ºC.
- Executive summary:
Determination of density was carried out in accordance with CIPAC MT 3.2.1 (equivalent to OECD 109 Guideline and EU method A.3), with GLP. The density determination of the tested material was performed using the Gay-Lussac pycnometer. Two measurements were performed and considered enough as the difference between results was less than 0.03 g/ml. The average measured absolute density of the tested material at 20°C was 1.5350 g/mL. The average calculated relative density of the tested material at 20°C was 1.5350.

Description of key information
Key study: Test method according to CIPAC MT 3.2.1 (equivalent to OECD 109/ EU Method A.3), GLP study. The measured absolute density of the tested material at 20°C was 1.5350 g/mL and the calculated relative density was 1.5350 at 20ºC.
Supporting studies: Data from peer reviewed secondary sources. The test compound has a density of 1.530 g/cm3.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.535
