The vapour pressure of the test item was 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. Vapour Pressure and OECD 104 (2006). The obtained results are 0.025, 0.037 and 0.22 Pa at 20, 25 and 50 °C respectively.
The vapour pressure of the test item was calculated to be 0.037 Pa at 25 °C.
