Individual results
A measurement chamber with a volume of Vc= 141.8361 cm3and an expansion chamber with a volume of Vr= 69.3167 cm3were used.
Two test series with different weights were performed at ambient temperature (20.3 °C). For results see Table1 and Table2.

The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 and in the OECD 109 was determined to be:
D420= 1.22
