Applicant's summary and conclusion

Conclusions:
Density = 1.2792 g/cm3
Executive summary:

Density of the test item was determined with a gas pycnometer at 20 °C according to OECD guideline 109 (no GLP).


The density was calculated automatically as the quotient of mass and volume of the test item. A double determination was performed. The results are summarized in the table below.





















Experiment No.Density [g/cm3]
11.2832
21.2752
Average1.2792

Density of test item was determined with 1.2792 g/cm3 (20 °C). This corresponds to a relative density of 1.2792 (the ratio between the density of the test substance and the density of water determined at 4 ºC, at which temperature water has its maximum density, i.e. 0.999975 g/cm3).
