Applicant's summary and conclusion

Conclusions:
The relative density D20/4 of the substance was determined to be 1.51.
Executive summary:

The relative density of the solid substance was determined at 20°C using a gas comparison pycnometer in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300. The relative density D20/4 was determined in duplicate obtaining a mean value of 1.51.
