- Key result
- Auto-ignition temperature:
- 225 °C
- Atm. press.:
- ca. 1 018.5 - ca. 1 022 hPa
- Remarks on result:
- other: The lowest temperature at which ignition of the test substance occurred was 229°C.
- Conclusions:
- An auto-ignition temperature of 225°C at 1018.5 - 1022.0 hPa was determined for the substance in accordance with EU Method A.15 and in compliance with GLP. The result is considered reliable.
Reference
Preliminary test:
The estimated auto-ignition temperature was 250°C.
Main test:
The results of the main study are reported in the table below. Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test, a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was <10°C.
The lowest temperature at which ignition of the test substance occurred was 229°C. This temperature was rounded off to the nearest multiple of 5°C giving an auto-ignition temperature of the test substance of 225°C at 1018.5 - 1022.0 hPa.
