- Guideline:
- DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
- Version / remarks:
- 2003-05
- Deviations:
- no

- no
- Key result
- Auto-ignition temperature:
- 249 °C
- Remarks on result:
- other: Atmospheric pressure not specified
- Conclusions:
- Under the conditions of this study the autoignition temperature of the test material has been determined to be 249 °C.
- Executive summary:
The auto-ignition temperature of the test material was determined in accordance with the standardised guideline DIN 51794, using the Petrotest ZPA 3 with automated Test Programs.
The measurements were performed with heating from 25 up to a maximum of 650 °C. The range-finder program heated at 5 K/min to determine an approximate temperature in 20 K steps. Program A then determined the minimal auto-ignition temperature in 5 K steps followed by Program B which determined the minimal auto-ignition temperature in 2 K steps.
Under the conditions of this study the auto-ignition temperature of the test material has been determined to be 249 °C.
Reference
Uncorrected value from measuring device = 253 °C
Corrected value = 0.985 x 253 = 249 °C
Description of key information

Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 249 °C
Additional information
The auto-ignition temperature of the test material was determined in accordance with the standardised guideline DIN 51794, using the Petrotest ZPA 3 with automated Test Programs. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The measurements were performed with heating from 25 up to a maximum of 650 °C. The range-finder program heated at 5 K/min to determine an approximate temperature in 20 K steps. Program A then determined the minimal auto-ignition temperature in 5 K steps followed by Program B which determined the minimal auto-ignition temperature in 2 K steps.
Under the conditions of this study the auto-ignition temperature of the test material has been determined to be 249 °C.
