Additional information

The relative density (and density) of the test material was investigated in accordance with the standardised guidelines OECD 109, EU Method A.3 and EPA OPPTS 830.7300, under GLP conditions, using a gas comparison stereopycnometer. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

Under the conditions of the study the relative density and density of the test material were determined to be 1.66 and 1.66 g/cm³, respectively at 20°C.
