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 < 20°C. According to the guidelines, no further testing was required.
The lowest temperature at which ignition of the test substance occurred was 482°C. This temperature was rounded off to the nearest multiple of 5°C giving an auto-ignition temperature of the test substance of 480°C.
Conclusion
The auto-ignition temperature of the test substance was determined to be 480 °C (998.3 - 1020.9hPa) according to EU Guideline A.15.
Description of key information
480 °C at 1013 hPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 480 °C
Additional information
The auto-ignition temperature was determined according to EU Method A.16.
