- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- Test substance has a vapour pressure of 2.7E-09 Pa at 20 °C.
- Executive summary:
The vapour pressure of the test item was determined by the gas saturation method in accordance with OECD TG 104 and in compliance with GLP. The vapour pressure of the test item, measured at 20 °C was 2.7E-09 Pa and at 25 °C was 6.6E-09 Pa.
