Applicant's summary and conclusion

Conclusions:
The density of the test substance was determined to be 1.1405 ± 0.00056 g/cm3 at 19.6 ± 0.3°C.
Executive summary:

The density of the test substance was determined in accordance with OECD Test Guideline 109. For the density determinations, the sample cup of the pycnometer was packed with the test substance to at least 2/3 capacity and the weight was recorded. The weight of the sample was calculated by subtracting the mass of the empty cup from the mass of the cup and the test substance. The sample was then analysed by placing the cup in the chamber cell of the pycnometer and three replicate analyses were performed by the instrument. The sample was removed from the pycnometer. Additional test substance was added to the pycnometer cup, packed firmly, and weighed. The sample cup was then placed in the pycnometer and triplicate analyses were performed. The procedure was repeated once more for a total of three sample weights.

 

The density of the test substance was determined to be 1.1405 ± 0.00056 g/cm3 at 19.6 ± 0.3°C.
