- Conclusions:
- The vapour pressure of the test item is 7.79E-7 Pa at 20ºC and 2.45E-6 Pa at 25ºC
- Executive summary:
The vapour pressure of the test item using the effusion method with e Knudsen Cell was determined according to OECD guideline 104 and EU Method A.4, under GLP conditions. The method is based on the determination of the mass of test substance flowing out per unit of time of a Knudsen cell in the form of vapour, through a micro-orifice under ultra-vacuum conditions. The vapour pressure was determined to be 7.79E-7 Pa at 20ºC and 2.45E-6 Pa at 25ºC.
