- Executive summary:
A study was conducted according to Regulation (EU) No. 440/2008 method A.3 and OECD Guideline No. 109(2012) to determine the relative density of the test item. The density was determined in two assays. Using the pycnometer method the density of the test item at 20.3 °C was determined to be 1.3874 g/cm3 and 1.3854 g/cm3, respectively. The mean relative density of the test item was determined to be 1.3864 at 20.3 °C.
