- Executive summary:
The vapour pressure of the test substance was determined according to OECD guideline 104 and EU method A.4. First, the effusion method was employed. The vapour pressure of the test item lay outside the determination limits of this method. Therefore, a study plan amendment was issued, and the static method was employed. Using the static method, vapour pressures of 443 Pa at 20 °C and 508 Pa at 25 ° C were determined. These values were calculated from the regression of 22 individual measurements.
Reference
Three measurement series were performed. The first measurement series was made using the effusion method. This method didn’t yield utilisable results, as the vapour pressure of the test item was much too high for this method. Therefore, a study plan amendment was issued, and the static method was employed. In the second measurement series, the static method was used, but due to an instrumental failure, no reliable values could be determined. Therefore, a new manometer (calibrated by DKD) was bought, and the measurement series were repeated with the new instrument. The third measurement series comprised two experiments. In the first experiment, the deviation between measurement at increasing and at decreasing temperatures was too high. Therefore, a second experiment was conducted. In this experiment, the vapour pressure of the test item was determined as 443 Pa at 20.0 °C, and 508 Pa at 25 °C.
