Preliminary test

The estimated auto-ignition temperature was 265°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 < 10°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test substance occurred was 250°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 of the substance was determined to be 260 °C at 1012 and 1027 hPa.

Executive summary:

The auto-ignition temperature was determined using EU Method A.15 under GLP. 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. 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 < 10°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test substance occurred was 250°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test substance. Under the conditions of the study, the auto-ignition temperature was determined to be 250 °C at 1012 and 1027 hPa.
