Description of key information
311 °C at 100.3 kPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 311 °C
Additional information
The auto-ignition temperature of the substance was determined according to EU Method A.15 using a hot flask test set-up. No cool flames were observed. The sample ignited with a yellow flame.
