Mean reference cell volume: 90.797 cm3

Mean sample cell volume: 149.012 cm3

As the reference cell volume and sample cell volume were within the defined tolerances (90.953 ± 1.0 cm3 and 149.225 ± 1.0 cm3 for the reference and sample cell volumes respectively) the gas comparison pycnometer was considered acceptable for use.

Overall mean density: 1.02 x 103 kg/m3

Relative density: 1.02

Temperature: 20.0 ± 1.0°C

Due to the test item’s viscosity, it was considered that the pycnometer method for liquids would be impractical. To aid transferal to glass vessels which would fit inside the sample cell of the gas comparison pycnometer, the test item was heated in a water bath at up to 60 °C in order to make it mobile enough to pour. The samples were then equilibrated at 20 °C before being tested.

 Two determinations were performed to ensure a reproducibility of less than ± 20 kg/m3 was obtained.

Conclusions:

The density of the test item has been determined to be 1.02 x 103 kg/m3 at 20.0 ± 1.0 °C and a relative density of 1.02.

Executive summary:

Density. 1.02 x 103 kg/m3 at 20.0 ± 1.0 °C, relative density of 1.02, by gas comparison pycnometer, designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012.
