- Executive summary:
Method
The density of the test item was determined in a GLP-compliant study using a gas comparison pycnometer according to the EU A.3 . The experiment is deemed valid, conclusive and thus suitable for assessment without restrictions.
Result
The relative density was measured to be 1.0872 at 20.0 ± 0.5 °C.
