Additional information

The vapour pressure of the test material was investigated in accordance with the standardised guidelines OECD 104 and EU Method A.4 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).

The vapour pressure was determined using a vapour pressure balance. A sequence of runs was started after a sample of test material had been under vacuum for approximately 25.5 hours. Temperature and pressure readings were taken between 240 and 250 °C with a one hour dwell at 240 °C between runs.

The vapour pressure of the test material has been determined to be less than 2.0 x 10^-5 Pa at 25 °C.
