- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 26 December - 27 December 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, and under GLP. The test substance is adequately characterised. Therefore full validation applies.

- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- DIN EN 14522, Method P (Determination of the auto ignition temperature of gases and vapours)
- Version / remarks:
- 2005
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes
- Remarks:
- Inspected on 4,5 and 6 July 2016/ Signed on 10 January 2017
- Key result
- Auto-ignition temperature:
- 442 °C
- Atm. press.:
- >= 958 - <= 977 hPa
- Conclusions:
- The auto-ignition temperature of test item was determined to be 442°C (lowest value of three determinations).
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 performed in order to determine the auto-ignition temperature of test item according to EU A.15 guideline.
The auto-ignition temperature of test item was determined to be 442°C (lowest value of three determinations). This value was determined using approximately 5 drops of test substance between 958 and 977 hPa.
Reference
Three trials were conducted. In the first one, the preselected auto-ignition temperature was set to 150°C but no ignition occurred and the test stopped automatically.
In the second one, the preselected auto-ignition temperature was set to 350°C but no ignition occurred and the test stopped automatically.
In the third one, the preselected auto-ignition temperature was set to 550°C. The auto-ignition of the substance was tested in varying amount of substance (between 2 and 11 droplets) and temperature (between 447 and 459°C).
Finally, three determinations were performed and then, three lowest auto-ignition temperatures were recorded as 449°C, 454°C and 452°C respectively using 5, 5 and 8 droplets.
As these temperatures did not differ by more than 2%, these results were considered as valid and the lowest value (449°C) was retained. As described in DIN EN 14522:2005, the final auto-ignition temperature was obtained in reducing the retained value by the absolute deviation calculated using the reproducibility value (1.5% relative).
This value was rounded to the nearest 1 °C and a final auto-ignition temperature of 442°C was obtained.
Moreover, the apparatus control was performed less than 6 months before the test (control between 18 October 2017 and 20 October 2017 and measurements dated on 26 to 27 December 2017). The lowest auto-ignition temperature measured for each reference substance did not differ by more than 1.5% from the reference value.
Therefore, the results of this study were considered as valid.
Description of key information
The auto-ignition temperature of test item was determined to be 442°C between 958 and 977 hPa. (lowest value of three determinations)
No particular hazard is anticipated in normal conditions of storage.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 442 °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.
