- #1
- Temp.:
- 25 °C
- Vapour pressure:
- 0.013 Pa
- Key result
- Test no.:
- #2
- Temp.:
- 70 °C
- Vapour pressure:

Description of key information
The vapour pressure of the test substance was determined at two temperatures using the vapor pressure balance method, designed to be compatible with EU Method A.4 and OECD 104. The vapour pressure of the test material was determined to be 1.27E-02 Pa at 25 °C and 0.149 Pa at 70 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.013 Pa
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
