Applicant's summary and conclusion

Conclusions:
The relative density D20/4 of the substance was determined to be 1.09.
Executive summary:

The relative density of the substance was determined in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300 (method: air comparison pycnometer (for solids)).

A gas comparison pycnometer was used with Helium as the gas. The relative density D20/4 was determined in duplicate obtaining a mean value of 1.09.
