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

- Key result
- Auto-ignition temperature:
- 390 °C
- Atm. press.:
- ca. 99.7 kPa
- Conclusions:
- Under the study conditions, the auto ignition temperature of the test substance was determined to be 390°C at 99.7 kPa.
- Executive summary:
A study was conducted to determine the auto ignition temperature of the test substance, according to EU Method A.15. The auto ignition temperature was determined in three independent determinations. A lowest value of the main test of 391 °C was found therefore, the auto-ignition temperature according to EU A.15 (rounded down to a whole multiple of 5 °C). Under the study conditions, the auto ignition temperature of the test substance was determined to be 390°C at 99.7 kPa (Krebs, 2018).

*The temperature was selected at the ZPA3 corresponding to an initial oven temperature of 200°C. As the test substance showed no ignition at 385.7 °C, a higher temperature was selected
for the subsequent ignition trials corresponding to a new initial oven temperature of 400°C. Using a constant heating rate, the subsequent ignition trials were conducted every 20 ± 5 K.
Atmospheric pressure during the pre-test was 99826 Pa.
