GUIDELINE
The determination was carried out using a procedure designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
RESULTS
Vapour pressure was determined to be 9.0 x 10E-02 Pa at 25 °C (298.15 K), 0.46 Pa at 40 °C (313.15 K) and 4.4 Pa at 90 °C (363.15 K).
