- Executive summary:
VAPOUR PRESSURE
In compliance with Commission Regulation (EC) No. 761/2009 - EC A4 method (2009) and OECD Guideline No. 104 (2006)
Method
Knudsen cell effusion method coupled to a micro-balance.
The vapour pressure is calculated from the experimental data using the Knudsen equation
Then, log P is plotted versus 1/T to extrapolate the vapour pressure at 25 °C (linear relationship)
The vapour pressure of the test item extrapolated at 25 °C is P = 3.8 × 10-3 Pa.
