Description of key information

330.7 °C (at 920 hPa)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
330.7 °C

Additional information

The auto-ignition temperature of the substance was assessed according to the EU Method A.15 and ASTM E659 -78. The test was performed in duplicate to determine the break point between ignition and non-ignition. Auto-ignition was evidenced by the sudden appearance of a flame inside the flask and by sharp rise in the temperature of the gas mixture. The lowest internal flask temperature at which hot-flame ignition occurs is considered as the hot-flame auto ignition temperature (AIT) of the substance in air at atmospheric pressure. Ignition delay times were measured in order to determine the ignition delay-ignition temperature relationship. 

Auto-ignition temperature, at 920 hPa is 330.7 °C, ignition delay time 2 s.
