- Key result
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- < 0.5 kPa
- Conclusions:
- Under the conditions of this study the vapour pressure of the test material was considered to be less than 0.5 kPa at 20°C.
- Executive summary:
The vapour pressure of the test material was investigated in accordance with the standardised guidelines OECD 104 and EU Method A.4., under GLP conditions.
After filling approximately 1 mL of the test material into the sample cup, the stirring magnet was inserted into the cup and it was placed into the tester. Dissolved air was removed from the sample by evacuation at 20°C. The vapour pressure as a function of temperature was registered in 20-100°C range in 5°C steps. The lowest reliable vapour pressure was 0.5 kPa.
Measured vapour pressures were less than the lowest pressure that can be reliably determined with MINIVAP VOC automatic vapour pressure tester.
Therefore, under the conditions of this study the vapour pressure of the test material was considered to be less than 0.5 kPa at 20°C.
Reference
Measured vapour pressures were less than the lowest pressure that can be reliably determined with MINIVAP VOC automatic vapour pressure tester. Therefore, the vapour pressure of the test material was considered to be less than 0.5 kPa at 20°C.
Description of key information

Key value for chemical safety assessment
Additional information
The vapour pressure of the test material was investigated in accordance with the standardised guidelines OECD 104 and EU Method A.4., under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
After filling approximately 1 mL of the test material into the sample cup, the stirring magnet was inserted into the cup and it was placed into the tester. Dissolved air was removed from the sample by evacuation at 20°C. The vapour pressure as a function of temperature was registered in 20-100°C range in 5°C steps. The lowest reliable vapour pressure was 0.5 kPa.
