Results and discussion

Auto-ignition temperature (liquids / gases)
Key result
Auto-ignition temperature:
340 °C
Atm. press.:
>= 994.8 - <= 996.9 hPa

Any other information on results incl. tables

Preliminary test:

The lowest temperature at which an ignition occurred was 361°C.

Main test:

Based on the results of the main test series, the lowest auto-ignition temperature was 343°C, see table below.

 Main test series  Lowest temperatures of an ignition  Highest temperatures without an ignition  Atmospheric Pressure
 1  361°C  359°C  995.7 - 995.8 hPa
 2  356°C  353°C  994.8 - 996.2 hPa
 3  343°C  341°C

 996.7 - 996.9 hPa

Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5°C was determined as 340°C.
