The empty sample vial was weighed and subsequently filled to approximately three-quarters full with the test substance. The contents were compacted by lightly jarring the vial on the bench surface. Reweighing yielded a net sample weight of the test substance of 3.0616 g. The sample vial was then inserted into the sample chamber, the lid tightly affixed, and the measurement procedure in the instrument started. The measurement cycle comprised five individual measurements.

























Value-No. 11.1686
Value-No. 21.1684
Value-No. 31.1683

Value-No. 51.1683

Mean density ρPR for the test series: 1.1684 g/cm3


The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.168.

Conclusions:
The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.168.
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 1.168.

Description of key information

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.168.

Key value for chemical safety assessment

Relative density at 20C:
1.168

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. 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= 1.168.
