Results and discussion

Auto-ignition temperature (liquids / gases)
Auto-ignition temperature:
460 °C
Atm. press.:
1 015.9 - 1 024.5 hPa
Remarks on result:
other: The lowest temperature at which ignition of the test substance occurred was 461°C. This temperature was rounded off to the nearest multiple of 5°C.

Any other information on results incl. tables

With each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 20°C.
