Applicant's summary and conclusion

Conclusions:
The relative density D20/4 of the substance was determined to be 1.39.
Executive summary:

The relative density of the 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, resulting in a mean value of 1.39.
