Additional information

A study was conducted according to OECD TG 104, Regulation (EC) No 440/2008 method A.4 and OPPTS 830.7950 to determine the vapour pressure of the test item. The vapour pressure of the test item was determined at three different temperatures (30, 45, 60 and 75 °C) using the effusion method (weight loss). All measured values showed good to medium reproducibility, giving relative standard deviations of less than 30 %, and perfect correlation. Therefore, the result of the test according to the guideline criteria was considered to be valid. The vapour pressure was calculated using the linear regression equation of the Log P versus 1/T function. The vapour pressure was calculated to be 0.000987 Pa at 20 °C and 0.00138 Pa at 25 °C respectively.
