Reference
The lowest temperatures at which an ignition occurred in the main test are given in the following table.
Table 1: Results of the main test
| Main test series | Lowest temperatures of an ignition [°C] | Highest temperatures without an ignition [°C] | Atmospheric Pressure [hPa] |
| 1 (ZT2) | 438 | 436 | 1008.3 |
| 2 (ZT2) | 435 | 433 | 1008.3 |
| 3 (ZT2) | 429 | 428 | 1008.3 |
| 4 (ZT3) | 436 | 435 | 1010.9 – 1011.3 |
Based on the results of the main test series, the lowest auto-ignition temperature was 429 °C.
