Hot flame autoignition temperature (AIT, °C) : 386

No cool flames were observed. Ignition produced an orange flame. The time lag to autoignition was 4 seconds.

Description of key information

Autoignition temperature (EU-method A.15): 386 °C at atmospheric pressure

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
386 °C

Additional information

The autoignition temperature for the test item was determined according to EU-method A.15.

Hot flame autoignition temperature (AIT, °C) : 386

No cool flames were observed. Ignition produced an orange flame. The time lag to autoignition was 4 seconds.

According to (1), the phenomenon of self-heating applies only to solids, liquids are not classified as self-heating. Thus, no classification requirements are associated with this result.
