Results
Preliminary Test
Table 1 displays the results, an ignition is denoted as “+” and no
ignition is denoted as “-“. At each temperature, 5 drops were put into
the Erlenmeyer flask. The atmospheric pressure was 1008.4 hPa.

Based on main test series results, the lowest auto-ignition
temperature was 445 °C.
Regulation EC No. 440/2008 and DIN 51794: the auto-ignition temperature
rounded down to the nearest multiple of 5°C was determined to be 440 °C.
DIN EN 14522: the auto-ignition temperature reduced by 1.5% and rounded
to the nearest integer temperature was determined as 437 °C.
Description of key information
440 °C at 1008.9 to 1011.5 hPa (EU Method A.15.)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 440 °C
