Executive summary:

The substance density was evaluated in accordance with OECD Test Guideline 109 and EC No. 440/2008 Method A.3 via a GLP laboratory. The density of solids is determined with a calibrated gas comparison pycnometer at a temperature of 20 °C ±0.01 °C. A pressurized gas (He) is expanded from a pressurized reference chamber into a sample chamber in which the test item is placed under atmospheric pressure. The volume of the sample chamber (24.9 cm³) as well as the volume of the reference chamber (21.3 cm³) are exactly known. The free volume of the sample chamber into which the gas is expanded can be calculated by the ideal gas law. With the free gas volume of the sample chamber, the volume of the test item in the sample chamber can be calculated by subtracting the free gas volume from the total chamber volume. By measuring the mass of the test item, the density is determined. The relative density D₄²⁰is obtained by dividing the measured density of the test item by the density of water at 4 °C (0.9999750 g/cm³). The density was determined as 0.92658 at 20 °C with a relative density of 0.9265 at 20 °C.
