Additional information
The density of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guideline EU Method A.3., using a gass pynometer. The study was assigned a reliability score of 1 in line with the principles for assessing data quality as defined by Klimisch (1997).
Under the conditions of the study, the relative density of the test material was determined to be 1.49 at 20.8 ± 0.5 °C, average of two determinations.
