Conclusions:
The density of the test item was determined to be 0.9825 ± 0.0003 at 20 °C ± 0.4 °C and the relative density was determined to be 0.9825 respectively.
Executive summary:

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. The density was determined in two independent determinations. Using the pycnometer method the density was determined to be 0.9825 ± 0.0003 g/cm3 at 20 ± 0.4 °C. The relative density of the test item was determined to be 0.9825 respectively. The standard deviation reflects the distinguished correlation of the two determinations. Thus, the study was regarded to valid.
