The test material did not change in appearance under the conditions used in the determination.
A total of 8 runs were completed for the main sequence. The first 6 runs were used as equilibrium had been reached; the final 2 runs were not used due to the nature of the plot obtained.
Description of key information
The vapour pressure of the test material was determined to be 56.0 Pa at 25 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 56 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 104 and EU Method A.4, under GLP conditions, using the vapour pressure balance method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of the study the vapour pressure of the test material was determined to be 56.0 Pa at 25 °C.
