- Guideline:
- EPA OPPTS 830.7950 (Vapor Pressure)
- Deviations:
- yes
- Remarks:

- Type of method:
- gas saturation method
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.5 Pa
- Remarks on result:
- other: Average of three sampling time-points
- Conclusions:
- Vapour pressure of the test substance: 0.5 Pa at 20°C
- Executive summary:
The vapour pressure of the test material has been determined to be 0.5 Pa at 20°C using the Gas saturation method (OECD guideline No. 104).
Therefore:
Vapour pressure of the test material: 0.5 Pa at 20°C
Reference
Headspace vapour concentrations of the test substance as found after an equilibration time of 96, 120, 144, 168 and 240 hours are exposed in the table below:
| Equilibration time (h) | Headspace concentration (microg/L) | Headspace concentration (g/m3) |
| 96 | 36.5 | 0.365 |
| 120 | 32.0 | 0.320 |
| 144 | 32.4 | 0.0324 |
| 168 | 31.8 | 0.0318 |
| 240 | 32.9 | 0.0329 |
The vapour pressure at 20°C was calculated from the average headspace concentration of 144 h, 168 hand 240 h samplings using equation described in material and methods section.
The result was 0.5 Pa.
Description of key information
The vapour pressure of the test material has been determined to be 0.5 Pa at 20°C using the Gas saturation method (OECD guideline No. 104).
Therefore:
Vapour pressure of the test material: 0.5 Pa at 20°C
Key value for chemical safety assessment
- Vapour pressure:
- 0.5 Pa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
