The mean density for the two test series is 1.29 g/cm3. Thus, the relative density (compared to water at 4 °C) is 1.29 ± 0.01.

Conclusions:
The relative density of the test item was determined according to the European Commission Regulation (EC) No. 440/2008 and OECD test guideline 109 by gas comparison pycnometer method and is 1.29 at 20 °C.
Executive summary:

The relative density of the test item was determined according to the European Commission Regulation (EC) No. 440/2008 and OECD test guideline 109 by gas comparison pycnometer method and is 1.29 at 20 °C.
