- Executive summary:
This study was conducted to determine the vapour pressure of the test substance according to the regulatory guidelines EC Method A.4, OPPTS 830.7950 and OECD 104. The vapour pressure was determined by the effusion method using isothermal thermogravimetry analysis.
The vapour pressure of the test item was determined to be 0.50 Pa (3.7E-3 mm Hg) at 20°C and 0.82 Pa (6.1E-3 mm Hg) at 25°C.
