+ positive response (flame, blast or deflagration)

- negative response (nothing or smoke only in 300 s period).

Conclusions:
The auto-ignition temperature of the test material was determined to be between 280 °C and 290 °C.

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.
