Reference
Based on results of the main test series, the auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 255 °C.
- EC No. 440/2008 and DIN 51794: the auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 255 °C.
- DIN EN 14522: the auto-ignition temperature reduced by 1.5% and rounded to the nearest integer temperature was determined as 256 °C.

Description of key information
The auto-ignition temperature (liquids) was determined to be 255 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 255 °C
Additional information
The auto-ignition temperature was determined in a study according to EC No. 440/2008 Method A.15 and in compliance with GLP criteria. In this study the lowest temperature at which a gas/air- or vapour/air-mixture of the flammable test item ignites in contact with a hot surface was determined. This is assessed by varying the amount of test item and the test temperature. The lowest temperature is rounded down to the nearest multiple of 5 °C. The auto-ignition temperature was determined to be 255 °C.
