Applicant's summary and conclusion

Conclusions:

The density of the test substance was determined using a pycnometer method according to OECD 109 and ASTM D5965-96 (method B) guidelines. The density was determined to be 1.045 g/mL, at 22.8 °C. No value for the relative density at 20 °C can be provided.

Executive summary:

The density of the test substance has been determined according to EC A.3 method and OECD test guideline 109. A helium pycnometer was used for the determination of the density. The density of the test substance at 22.8 ºC was 1.045 g/cm³.
