Applicant's summary and conclusion

Conclusions:
A gas comparison pycnometer was used for the determination of the density and relative density of the substance in accordance with OECD 109 (1981), EU Method A.3 (1984) and GLP. The density of the test substance at 20ºC was 1.22 g/cm3. The relative density was 1.22.
