- Test no.:
- #1
- Temp.:
- 110 °C
- Vapour pressure:
- > 34 - < 38 Pa
- Test no.:
- #2
- Temp.:
- 120 °C

- > 75 - < 81 Pa
- Test no.:
- #3
- Temp.:
- 130 °C
- Vapour pressure:
- > 150 - < 160 Pa
- Test no.:
- #4
- Temp.:
- 140 °C
- Vapour pressure:
- > 290 - < 300 Pa
- Conclusions:
- The vapour pressure of the test item at 20 and 25°C is respectively 0.005 and 0.0095 Pa
- Executive summary:
The test item vapour pressure was determined with isothermal thermogravimetric effusion method according to recognised guidelines and under GLP.
No deviation from these guidelines was observed during the study.
The vapour pressures apparatus was validated between 10-8to 103Pa using a set of reference substances with known vapour pressure.
The test item vapour pressure at 20 and 25°C have been determined with the vapour pressure regression curve. These values are respectively 0.005 and 0.0095 Pa.
Reference
The test item vapour pressures calculated with the vapour pressure regression curve are : 0.005 Pa at 20°C and 0.0095 at 25°C
Description of key information
The test item vapour pressure was determined in an experimental key study (Klimisch validity one, according to recognised guidelines).
Key value for chemical safety assessment
- Vapour pressure:
- 0.005 Pa
- at the temperature of:
- 20 °C
