Additional information

The key study was conducted in line with GLP and the standardised guidelines OECD 104 and EU Method A.4. It was assigned a reliability score of 1 in accordance with the criteria detailed by Klimisch (1997).

The vapour pressure of the test material was determined using the vapour pressure balance method.

A sequence of runs was started after a sample of test material had been under vacuum for approximately 69 hours. Temperature and pressure readings were taken between 40 and 50 °C with a one hour dwell at 40 °C between runs. The vapour pressure of the sample was measured over a range of temperatures to enable extrapolation to 298.15 K. The data from 7 runs was used to calculate an average value.

Under the conditions of this study, the vapour pressure of the test material was determined to be 5.2 x 10-2 Pa at 25 °C.
