- Executive summary:
The aim of this study was the determination of the vapour pressure of the test substance according to the OECD Guideline 104 with GLP. The method for analysis was the effusion method: Knudsen cell and the apparatus. This parameter was determined at 20ºC and 25ºC. The vapour pressure of the test substance was 5.03*10E-03 Pa at 20ºC and 1.01*10E-02 Pa at 25ºC under the specified conditions.
