- Key result
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- >= 0 - < 0 hPa
- Key result
- Test no.:
- #2
- Temp.:
- 25 °C
- Vapour pressure:
- >= 0 - < 0 hPa
- Conclusions:
- The vapour pressure of the substance at 20°C (293K) is < 1.3E-8 Pa and at 25°C (298K) is < 1.9E-8 Pa.
- Executive summary:
The calculated vapour pressure of the substance was outside of the validated range of the method. Therefore vapour pressure of the substance is reported as less than the vapour pressure of bezo(ghi)perylene i.e. the reference substance with the lowest vapour pressure used during validation of the method.
Reference
The calculated vapour pressure of the substance (Table 4) was outside of the validated range of the method. Therefore vapour pressure of the substance is reported as less than the vapour pressure of bezo(ghi)perylene i.e. the reference substance with the lowest vapour pressure used during validation of the method.
Description of key information
The calculated vapour pressure of the substance was outside of the validated range of the method. Therefore vapour pressure of the substance is reported as less than the vapour pressure of bezo(ghi)perylene i.e. the reference substance with the lowest vapour pressure used during validation of the method.
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
