Description of key information
Autoignition temperature: 280 °C - 290 °C (EU method A15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 280 °C
Additional information
Bolzonella (2011) determined that the autoignition temperature of the substance was 290 °C ± 10 °C using EU method A15. The lowest temperature giving a positive effect was 290 °C. At a temperature of 280 °C, no ignition was observed. For the purpose of the "key value for chemical safety assessment", the lower value of 280 °C has been used.
