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
The vapour pressure of the test item was determined to be 7.32 x 10E-02 Pa at 25 °C (298 K) and 1.23 Pa at 70 °C (343K).
