Key study


BATELLE (2003)


An experimental study was conducted to determine the vapour pressure of the test item according to EU directive 91/414/EEC (Annex II) amended by directive 94/37/EC, method A.4 using the gas saturation method. Three to four runs were carried out at 30, 40 and 50 °C with flow rates at 5, 10, 15 and 20 mL/min. The test item was trapped in glass impinge filled with acetone. The amount of test item was determined by HPLC. The vapour pressure was determined to be 9.16E-07, 2.22E-06, 7.33E-06 and 1.30E-05 Pa at 20, 30, 40 and 50 °C, respectively.


Supporting information


TNO  (1988)


An experimental study was conducted to determine the vapour pressure of the test item according to OECD Test Guideline 104 using the gas saturation method. The maximum vapour pressure of the test item determined experimentally at 35 °C is equal to or lower than 5.6E-08 Pa. From the latter value the maximum vapour pressure at 25 °C is calculated based on the modified Watson Correlation to be 1.3E-08 Pa.
