Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 18 to 20th July 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method. The substance is considered to be adequately characterised. Therefore full validation applies.
- 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)
- Version / remarks:
- 2003
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected on 13 and 14 October 2014 / signed on 08 April 2015
- Key result
- Auto-ignition temperature:
- ca. 285 °C
- Atm. press.:
- >= 99 410 - <= 100 083 Pa
- Conclusions:
- Under the test conditions, the auto-ignition temperature of the test item was stated as 285°C between 99,410 and 100,083 kPa.
This parameter/method is not relevant for classification, however the information is useful regarding potential additional fire hazard. No particular hazard is anticipated in normal conditions of storage. - Executive summary:
The study was conducted according to procedure and demands of EU-Method A.15 and DIN 51794.
The auto ignition temperature was determined in three independent determinations. The lowest value of the auto ignition temperature is 289 °C. This value was determined using 5 drops of test substance. The test substance showed auto ignition after 18 and 20 seconds.
Due to safety reasons and according to the guidelines the auto ignition temperature (result of determination) is the lowest value from the lowest values of the experiments, rounded down to a whole multiple of 5 °C.
Therefore, the auto-ignition temperature of the test item is stated as 285 °C (99410 -100083 Pa).

The lowest value of the auto ignition temperature is 289°C. This value was determined using 5 drops test item. The test item showed auto ignition after 18 and 20 seconds.
The auto ignition temperature (result of determination) is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 285 °C.
Validity
The requirements for precision of the DIN standard in case of one observer and one test system (no interlaboratory testing, no second observer) are stated as follows: Sufficient accordance is reached if the largest difference between measured temperatures was:
- at the most 5 °C for ignition temperatures up to 300 °C
- at the most 10 °C for ignition temperatures above 300 °C.
As these demands are not fulfilled, the higher temperature is discarded.
As no difference between three evaluated measured ignition temperatures, accordance with the demands of the DIN standard is given.
Description of key information
The test item has been determined to have an auto-ignition temperature of 285°C under the test conditions (99410 -100083 Pa).
This parameter/method is not relevant for classification, however the information is useful regarding potential additional fire hazard.
No particular hazard is anticipated in normal conditions of storage.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 285 °C
Additional information
A GLP study was performed in order to determine the auto-ignition temperature of the test substance in compliance with the EU-Method A.15 and stardard DIN 51794 listed in EU A15.
The auto ignition temperature was determined in three independent determinations. The lowest value of the auto ignition temperature is 289 °C. This value was determined using 5 drops of test substance. The test substance showed auto ignition after 18 and 20 seconds.
Due to safety reasons and according to the guidelines the auto ignition temperature (result of determination) is the lowest value from the lowest values
of the experiments, rounded down to a whole multiple of 5 °C.
Therefore, the auto-ignition temperature of the test item is stated as 285 °C (99410 -100083 Pa).
