- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- 31. May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
- Version / remarks:
- 2003
- Deviations:
- no

- Key result
- Auto-ignition temperature:
- 525 °C
- Atm. press.:
- 1 013.25 hPa
- Conclusions:
- The auto-ignition temperature of the test item was determined to be 525 °C at 1013.25 hPa.
- Executive summary:
Auto-ignition temperature of the test item was determined in three test series according to EU method A.15 and DIN 51794. The auto-ignition temperature is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C. The three lowest values of the main study lay within a range of 20 K as required for auto-ignition temperatures above 300 °C. Thus, the validity criterion which is demanded in the DIN standard was fulfilled. Auto-ignition temperature of the test item was determined to be 525 °C at 1013.25 hPa.
Reference
Table 1 Lowest Values main test
| Experiment | Value | Ignition delay | Drops used |
| First test series | 532 °C | 45 s | 1 |
| Second test series | 525 °C | 53 s | 1 |
| Third test series | 527 °C | 68 s | 1 |
The lowest value of the auto ignition temperature is 525 °C. This value was determined using 1 drop test item. The test item showed auto ignition after 53 seconds. The three lowest values of the main test lay within a range of 20 K (as required for auto ignition temperatures above 300 °C). The largest difference between measured ignition temperatures was 7 K.
Description of key information
The auto-ignition temperature of the test item was determined to be 525 °C at 1013.25 hPa.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 525 °C
