Preliminary test

The estimated auto-ignition temperature was 375°C.

Main study

Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 20°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test substance occurred was 355°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test substance.

Conclusions:
The auto-ignition temperature was determined to be 355 °C at 1002.2 and 1003.4 hPa.
Executive summary:

The auto-ignition temperature was determined using EU Method A.15. The auto-ignition temperature is the lowest temperature at which the test item will ignite when mixed with air under the conditions defined in the test method.
