Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:

- Adequacy of study:
- key study
- Study period:
- 25 Jul to 01 Aug 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))

- Remarks:
- Hess, Ministerium für Umwelt, Energie, Landwirtschaft und Verbraucherschutz, Wiesbaden, Germany
- Auto-ignition temperature:
- 565 °C
- Atm. press.:
- >= 1 002.8 - <= 1 008.1 hPa
- Conclusions:
- The test item has a self-ignition temperature of 565 °C.
- Executive summary:
The study was performed according to the European Commission Regulation (EC) No. 440/2008, Part A: Methods for the determination of physico-chemical properties A. 15. Auto-ignition temperature (liquids and of gases) and closely following the standard DIN 51794:2003-05 "Testing of mineral oil hydrocarbons - Determination of ignition temperature".
In the main test, the ignition at the lowest temperature at which an ignition in the preliminary test was observed is repeated, the temperature is decreased by 5 °C and the test is repeated. This procedure is repeated until no ignition is observed. Subsequently the amount of test item added to the apparatus is varied at the same temperature. If an ignition occurs during the variation of the amount of test item, the temperature is decreased again by 5 °C and the procedure started again. The test is continued by choosing the lowest temperature found in the previous step where an ignition occurred. The test temperature is lowered in intervals of approximately 2 °C until no ignition occurs within 5 min after introducing the sample amount of substance as found before. At that temperature where no ignition occurred within 5 min the amount of the test substance is varied stepwise until ignition occurs.
The main test (2 °C steps) is repeated at least two times to verify the result of the first main test (2 °C steps).
The lowest auto-ignition temperature of the test item was determined to be 568 °C in the main test. Due to safety reasons and according to the guidelines the lowest measured temperature at which an ignition was observed was rounded to the next lower number divisible by 5, giving a value of 565 °C.
