- Key result
- Temp.:
- 25.03 °C
- Vapour pressure:
- < 0 Pa
- Conclusions:
- The vapour pressure of test substance was lower than 4.0E-06 Pa at 25 °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 25 °C, was lower than 4.0E-06 Pa.
