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:
- August 14, 2019 - August 30, 2019
- 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))
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- equivalent or similar 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:
- no
- Specific details on test material used for the study:
- Storage conditions: Ambient temperature (10 °C to 30 °C)
- Key result
- Auto-ignition temperature:
- 355 °C
- Atm. press.:
- >= 1 006.9 - <= 1 016.6 hPa
- Conclusions:
- The auto-ignition temperature of the test item was 355 °C.
- Executive summary:
The study was performed in order to determine the auto-ignition temperature of test item according to EU A.15 guideline.The lowest auto-ignition temperature of the test item was determined to be 360°C in the main test.
The three lowest results of the tests with 2 K steps were within a range of 10K. Therefore, the results were considered as valid.
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 355 °C.
Reference

The lowest auto-ignition temperature of the test item was determined to be 360 °Cin 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 355 °C.
Description of key information
AIT for liquid and low melting point solids:
The auto-ignition temperature of the test item according to the auto-ignition test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.15. was 355 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 355 °C
Additional information
A fully reliable experimental study, conducted according to EU A.15 guideline is available.
It is considered as a key study, and the result is retained as key data.
This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
