Applicant's summary and conclusion

Conclusions:
The relative density D20/4 of the substance was determined to be 0.963.
Executive summary:

The relative density of the liquid substance was determined using the pycnometer method in a GLP study based on EC A.3, OECD 109 and OPPTS 830.7300. A 10 mL volume pycnometer was used. The relative density D20/4 was determined in duplicate at 20°C obtaining a mean value of 0.963.
