Executive summary:

A study was conducted to determine the relative density of the substance according to OECD Guideline 109. An empty and dry pycnometer was weighed. The test substance was then weighed into the pycnometer and covered with immersion liquid. Remaining air was removed by evacuation and the pycnometer was filled with immersion liquid and incubated for approximately 20 min at 20°C. Afterwards, the pycnometer was topped up to the mark, wiped and weighed. The difference of total weight and the weight of the pycnometer with test substance was the weight of the immersion liquid. The density of the used immersion liquid was then determined at 20°C. The pycnometer was filled with water, incubated at 20°C and weighed. This procedure was repeated for the immersion liquid. Under the study conditions, the relative density of the substance was determined to be 1.3198 at 20°C (Maas, 2016).
