Reference
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.
