Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
