- Executive summary:
The vapour pressure of the test substance was determined according to OECD 104/ EU Method A.4, under GLP conditions.The vapour pressure of the test item using the effusion method with Knudsen cell was determined to be 2.79 Pa at 20ºC and 5.59 Pa at 25 ºC.
Reference
Vapour pressure of the test item at 20ºC and 25ºC was calculated on the basis of equation log (p) = f (1/ t) = a-b/(t+273.15) where: p – vapour pressure in Pa, t – temperature in ºC, obtained for four measurement points: 28.50ºC, 31.30ºC, 34.10ºC and 37.00ºC. The graphic is included below.
