Conclusion
The auto-ignition temperature of the test item was 276°C ± 3°C (corrected temperature).
Description of key information
Auto-ignition temperature: 276 ± 3°C at 1013 hPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 276 °C
Additional information
A measured auto-ignition temperature value of 276 ± 3°C at 1013 hPa was determined for the registration substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
