Applicant's summary and conclusion

Conclusions:

The relative density of the test item has been determined to be 1.12 at 20.0 ± 0.5°C.

Executive summary:

Method

The determination was carried out using the pycnometer method, designed to be compatible with Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Procedure

A glass pycnometer of 10 ml nominal capacity was cleaned and dried to a constant weight. Distilled water and test item were equilibrated at 20.0 ± 0.5°C. A calibration was carried out by determining the mass of distilled water required to fill the pycnometer. The pycnometer was then emptied and dried to constant weight. The mass of test item required to fill the pycnometer was then determined.

Conclusion

The relative density of the test item has been determined to be 1.12 at 20.0 ± 0.5°C.
