- Conclusions:
- The vapour pressure of the test item was calculated for the temperatures 20, 25 and 50 °C by extrapolation of the measured vapour pressure curve, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline 104 (2006). The vapour pressure at 20°C was 3.7E-09, at 25°C 8.8E-09 and at 50°C 4.6E-07 Pa.
Reference
Effusion method: Knudsen cell
