Applicant's summary and conclusion

The relative density of the test material has been determined to be 1.37 g/cm3 at 21 ± 0.5oC
Executive summary:

The relative density has been assessed using a gas comparison pycnometer according to EU method A3 in compliance with GLP. Using a calibrated pycnometer, the relative pressure in comparison with the known volume of the sample cell was recorded in duplicate. An average relative density of the substance calculated to be 1.37g/cm3 at 21± 0.5oC
