- Executive summary:
The determination of the vapour pressure of the test substance was carried out according to the OECD Guideline 104 with GLP. The method for analysis was the effusion method: isothermal thermogravimetry. This parameter was determined at 20ºC and 25ºC. The vapour pressure of the test substance was 2.01531×10-12 Pa at 20ºC and 4.73376×10-12 Pa at 25ºC.
