- other: Mean of runs 1 and 2
- Conclusions:
- Under the conditions of the study the vapour pressure of the test material was 2 Pa at 20°C.
- Executive summary:
The vapour pressure of the test material was investigated in accordance with the standardised guideline EU Method A.4, under GLP conditions.
The static test method was performed using two runs, in the first run the sample was degassed for 65 hours prior to testing and in the second run the sample was degassed for 18 hours prior to testing.
Under the conditions of the study the vapour pressure of the test material was 2 Pa at 20°C.

*= Determined by extrapolation
- Run 1: The sample (11.7 g) was degassed for 65 hours prior to testing. The starting vacuum was 0.0011 mbar.
- Run 2: The sample (13.3 g) was degassed for 18 hours prior to testing. The starting vacuum was 0.0011 mbar.
Description of key information
Under the conditions of the study the vapour pressure of the test material was 2 Pa at 20°C.
Key value for chemical safety assessment
- Vapour pressure:
- 2 Pa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of the test material was investigated in accordance with the standardised guideline EU Method A.4, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The static test method was performed using two runs, in the first run the sample was degassed for 65 hours prior to testing and in the second run the sample was degassed for 18 hours prior to testing.
Under the conditions of the study the vapour pressure of the test material was 2 Pa at 20°C.
