- Executive summary:
The objective of this study was the determination of the vapour pressure of the test item by the Effusion method (Knudsen cell). Up to a temperature of 120 °C no vapour pressure could be detected. The vapour pressure was measured in the temperature range of 120 to 150 °C. The vapour pressure of the test item RCX15-116 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 Test Guideline 104 (2006).
