- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0 hPa
- Remarks on result:
- other: calculated vapor pressure value
- Conclusions:
- The vapour pressure of the test substance is 0.000082 hPa at 25 °C.
- Executive summary:
The study was performed to assess the vapor pressure. The study was conducted in accordance with EEC Method for "determination of the vapor pressure", Directive 92/69/EEC, method A.4 which is in most parts equivalent to the OECD Guideline for Testing of Chemicals No. 104. The vapor pressure of test substance is 0.000082 hPa at 25 °C.
Reference
Validity criteria for the measurement of the vapor pressure:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The vapour pressure should be determined for at least two temperatures. Three or more are preferred in the range 0 to 50 °C, in order to check the linearity of the vapour pressure curve. | The vapor pressure was determined at 11 temperatures ranging from 16 °C to 38 °C. | Yes |
| A log p versus 1 /T curve should be stated. | The curve was presented in the report. | Yes |
| An estimate of the vapour pressure at 20 or 25 °C should be stated. | The estimated vapor pressure at 20, 25 °C were given. | Yes |
