- Executive summary:
A study was conducted according to OECD TG 104, Regulation (EC) No 440/2008 method A.4 and OPPTS 830.7950 to determine the vapour pressure of the test item. A vapour pressure curve with 9 data points was measured over a pressure range between 12 to 62 hPa. For control 3 measuring points were evaluated with decreasing pressure. The vapour pressure was measured in the temperature range of 25 to 900 °C. From the measured data points of the vapour pressure curve the constants A, B and C of the Antoine equation was derived and the vapour pressure of the test item as calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. The vapour pressure of the test item was determined to be 0.07 Pa at 20 °C, 0.10 Pa at 25 °C and 0.38 Pa at 50 °C respectively. No observations were made which cause doubt on the validity of the outcome of the study.
