Conclusions:

The relative density of the test item was determined to be 1.524. The study is considered to be adequate and reliable.

Executive summary:

The determination of the relative density of the test item was performed in accordance with the OECD Guideline for Testing of Chemicals, No. 109, ”Density of Liquids and Solids”, using an air comparison pycnometer.

The test was performed at a temperature of 20.0 °C ± 0.1 °C. The determination of the relative density of the test item was performed with two independent test item samples each measured in triplicate.

The density of the test item was determined to be 1.524 g/cm³ at 20.0 °C ± 0.1 °C and the relative density was determined to be 1.524.
