- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:

- Key result
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- 37.4 Pa
- Key result
- Test no.:
- #2
- Temp.:
- 25 °C
- Vapour pressure:
- 63.87 Pa
- Conclusions:
- The vapour pressure was determined to be 37.40 Pa and 63.87 Pa at 20 ºC and 25 ºC respectively.
- Executive summary:
The vapour pressure determination was performed according to OECD Guideline 104 and EU Method A.4 (GLP study) by an effusion method using Knudsen cell. Vapour pressure at 20 ºC and 25 ºC was calculated on the basis of equation log (p) = f (1/t) = a-b/(t+273.15) where: p – vapour pressure in Pa, t – temperature in ºC, obtained for four measurement points: 23.8 ºC, 26.6 ºC, 29.4 ºC and 32.2 ºC. The vapour pressure was determined to be 37.40 Pa and 63.87 Pa at 20 ºC and 25 ºC respectively.
