- Executive summary:
The study was conducted under GLP according to standard DIN 51794:2003 (listed in EU A.15 guideline).
The auto ignition temperature was determined in three independent determinations.
Under the test conditions, the lowest value of the auto ignition temperature is 262 °C between 99.843 and 100.423 kPa.
This value was determined using 5 drops of test substance. The test substance showed auto ignition after 41 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 260°C between 99.843 and 100.423kPa.
Reference
The following lowest values were recorded:

The lowest value of the auto ignition temperatureis 262 °C. This value was determined using 5 drops test item. The test item showed auto ignition after 41 seconds.
The auto ignition temperature (result of determination) is the lowest value fromthe lowest values of the three experiments,rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 260 °C (99843 -100423 Pa).
Validity
In the DIN, the following limits are applied to the range of lowest values which may be used for evaluation:
Table 4.12/2.- Acceptable ranges.
Auto ignition temp. |
Range |
< 300 °C |
difference between three values of the main test max. 5 °C |
The three lowest values of the main test lay within a range of 5 °C (as required for auto ignition temperatures above 300 °C). The largest difference between measured ignition temperatures was 3 °C. The acceptable range which is demanded in the DIN standard was fulfilled.
All measured values show good correlation. No observations were made which might cause doubts concerning the validity of the study outcome.
Description of key information
The auto-ignition temperature of the substance is stated as 260°C under the test conditions (at 99843 -100423 Pa).
No particular hazard is anticipated in normal conditions of storage.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 260 °C
Additional information
A GLP fully reliable experimental study, conducted according to a recognized EU/DIN method, is available. Therefore, it is considered as a key study. 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.
