Executive summary:

A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of the test item. The density was determined in five independent determinations. Using the air comparison pycnometer method the density was determined to be 1.4824 ± 0.01384 g/cm3 at 20 ± 0.5 °C and the relative density 1.4824 with respect to water at 4 °C, respectively.
