- Key result
- Auto-ignition temperature:
- 345 °C
- Atm. press.:
- 999.5 hPa
- Conclusions:
- The test item has an auto-ignition temperature of 345°C.
- Executive summary:
The auto-ignition temperature of the test item was assessed according to EU method A.15 (EC No. 440/2008). In a preliminary experiment, an ignition temperature of 423°C was observed. The auto-ignition was further assessed in the main test. In total 5 measurements have been carried out. The lowest auto-ignition temperature was found to be 346°C. The auto-ignition temperature rounded down to the nearest multiple of 5°C was determined as 345°C.
Reference
The lowest temperatures at which an ignition occured are given below:
| Main test series | Lowest temperatures of an ignition | Highest temperatures without an ignition | Atmospheric Pressure |
| 1 | 374 °C | 372 °C | 1006.0 hPa |
| 2 | 374 °C | 372 °C | 1006.0 hPa |
| 3 | 347 °C | 343 °C | 1000.0 – 1002.5 hPa |
| 4 | 346 °C | 343 °C | 997.1 – 999.2 hPa |
| 5 | 346 °C | 343 °C | 999.5 – 999.6 hPa |
Based on results of the main test series, the lowest auto-ignition temperature was 346 °C.
The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 345 °C.
