Applicant's summary and conclusion

Conclusions:

The absolute density of the test substance is 1.42 g/mL at 20°C.

Executive summary:

The absolute density of the test substance was determined at 20°C using a Gay-Lussac Pycnometer according to the guidelines EPA OPPTS 830.7300 and OECD 109.  Triplicate measurements were made and averaged.  The capacity of the pycnometer was determined using deionised water at 20°C. In the determination of the test substance density, n-hexane was used as a wetting solution.  The densities of the test substance of triplicate samples at 20°C are 1.42, 1.43, and 1.41 g/mL, for an average of 1.42 ± 0.01 g/mL. The absolute density of the test substance is 1.42 g/mL at 20°C.
