- Executive summary:
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 by using the gas comparison pycnometer at 20.0 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item was determined to be D4R 1.22.
Reference
Two tests were performed at 20.6 °C.

Mean density ρPR for the two test series: 1.22 g/cm3
The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.22.
Description of key information
The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be 1.22.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.22
Additional information
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 by using the gas comparison pycnometer at 20 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item (calculated from the mean density of the test item) was determined to be D420= 1.22.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
