Description of key information
Auto-ignition temperature: 296 ± 5°C at 100.3 to 101.3 kPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 296 °C
Additional information
An auto-ignition temperature value of 296 ± 5°C at 100.3 to 101.3 kPa was determined for the submission substance in accordance with EU Method A.15 and in compliance with GLP. The result is considered to be reliable.
In a secondary source to which reliability could not be assigned, an auto-ignition temperature value of 360°C was reported for the substance.
