- Vapour pressure:
- 0 Pa
- Conclusions:
- The vapour pressure at 25°C of test material is 1.94 x 10^-10 mmHg or 2.59 x 10^-8 Pa. At 20°C, the vapour pressure of test material is 7.14 x 10^-11 mmHg or 9.52 x 10^-9 Pa.
- Executive summary:
The vapour pressure of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guidelines EPA OPPTS 830.7950 and OECD 104.
Based on measurements and extrapolation, the vapour pressure of the test material at 25 °C is 1.94 x 10-10 mmHg or 2.59 x 10-8 Pa. At 20 °C, the vapour pressure of test material is 7.14 x 10-11 mmHg or 9.52 x 10-9 Pa.
Reference
Based on measurements and extrapolation, the vapour pressure at 25 °C of test material is 1.94 x 10-10 mmHg or 2.59 x 10-8 Pa. At 20 °C, the vapour pressure of test material is 7.14 x 10-11 mmHg or 9.52 x 10-9 Pa.

Additional information
The vapour pressure of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guidelines EPA OPPTS 830.7950 and OECD 104. The study was assigned a reliability score of 1 in line with the criteria of Klimisch et al. (1997).
Based on measurements and extrapolation, the vapour pressure of the test material at 25 °C is 1.94 x 10-10 mmHg or 2.59 x 10-8 Pa. At 20 °C, the vapour pressure of test material is 7.14 x 10-11 mmHg or 9.52 x 10-9 Pa.
