Preliminary test

The estimated auto-ignition temperature was 275°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 262°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 260°C.

Conclusions:

The auto-ignition temperature of the test item was determined to be 260 °C at 1010 and 1015 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 item 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 item occurred was 262°C. This temperature was rounded to the lowest multiple of 5°C and therefore 260°C was given as the auto-ignition temperature of the test item. Under the conditions of the study, the auto-ignition temperature was determined to be 260 °C at 1010 and 1015 hPa.
