Description of key information
Auto-ignition temperature: 299±3°C at 1013 hPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 299 °C
Additional information
A measured auto-ignition temperature value of 299±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.
