Preliminary test:

The lowest temperature at which an ignition occurred was 483°C.

Main test:

Based on the results of the main test series, the lowest auto-ignition temperature was 468°C, see table

below.

 Main test series  Lowest temperatures of an ignition  Highest temperatures of an ignition  Atmospheric pressure
 1  468°C  465°C  998.8 - 1007.2 hPa
 2  476°C  474°C  998.8 hPa
 3  474°C  472°C

 998.8 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 465°C.
