Conclusions:

The density of the test item BLUE GS 5664.80 was determined to be 1.546 g/cm3 (= 1.546 · 103 kg/m3) at 19.7 °C ± 0.3 °C using a gas comparison pycnometer.

Executive summary:

The determination of the relative density of the test item was performed in accordance with the EEC Directive 92/69, Part A. Methods for the determination of physico-chemical properties, A.3 "Relative density" and the OECD Guideline for Testing of Chemicals, No. 109, "Density of Liquids and Solids" using a gas comparison pycnometer.

The test was performed at a temperature of 19. 7 °C ± 0.3 °C.

The calibration procedure was performed in triplicate. The determination of the relative density of the test item was performed with two independent test item samples each at least measured in triplicate.

The density of the test item BLUE GS 5664.80 was determined to be 1.546 g/cm3 (= 1.546 · 103 kg/m3) at 19.7 °C ± 0.3 °C using a gas comparison pycnometer.
