Conclusion:
The auto-ignition temperature of the test item was 294 ± 3°C (corrected temperature).
Description of key information
Auto-ignition temperature: 294 ± 3°C at 98.4 kPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 294 °C
Additional information
A measured auto-ignition temperature value of 294 ± 3°C at 98.4 kPa was determined for the registered substance using a relevant test method and in compliance with GLP. The result is considered to be reliable and is selected as key study.
In available secondary sources to which reliability could not be assigned, auto-ignition temperature values of 280°C and 290°C were reported for the substance.
