Applicant's summary and conclusion

Conclusions:
The relative density D20/4 of the substance was determined to be 0.940.
Executive summary:

The density of the substance was determined 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 0.940.
