m (Test Substance) = m (Pycnometer + Test Substance) - m (Pycnometer)

V (Test Substance) = V (Pycnometer)

Density [kg/m³] = (m (Test Substance) [g] / V (Test Substance) [cm³]) • 1000

Relative density = Density [kg/m³] / 999.972 [kg/m³] (Density of water at 4 °C)

Conclusions:

The relative density of the test substance at 20 °C was determined to be 1.468.

Executive summary:

The relative density of the test substance was determined according to EEC-Guideline 92/69/EEC A.3 and EPA OPPTS 830.7300 using the pycnometer method. Calibrated pycnometers were filled with the test substance and weighed afterwards. The test was performed twice. The relative density of the test substance was calculated from the masses of the pycnometer and the test substance, as well as of the volume of the empty pycnometer.The relative density of the test substance at 20.0°C (liquid) as mean of three determinations was determined to be 1.468.

Key study

The relative density of the test substance was determined according to EEC-Guideline 92/69/EEC A.3 and EPA OPPTS 830.7300 using the pycnometer method. Calibrated pycnometers were filled with the test substance and weighed afterwards. The test was performed twice. The relative density of the test substance was calculated from the masses of the pycnometer and the test substance, as well as of the volume of the empty pycnometer. The relative density of the test substance at 20.0°C (liquid) as mean of three determinations was determined to be 1.468.

Supporting study

A supporting study conducted according to the same guidelines and conditions like the key study was performed. A test substance with purity 34.5 % in a formulation was tested. The relative density at 20 °C was determined to be 1.162.
