Conclusion
The auto-ignition temperature of the test item was 227 ± 3°C (corrected temperature).
Description of key information
Auto-ignition temperature: 227 ± 3°C at 1013 hPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 227 °C
Additional information
An auto-ignition temperature value of 227 ± 3°C at 1013 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
