The relative density of test substance was determined using the gas comparison method at a temperature of 20 °C.

The determination of the relative density was performed by three-fold measurements of two independent test item samples. The individual readings are summarised in Table 1.

The density of test substance was determined to be 1.813 g/cm³ (= 1813 kg/m³) at 20 °C.
