Preliminary test

The estimated auto-ignition temperature was 375°C.

Main study

The results of the main study on the determination of the auto-ignition temperature of the test substance are given in the table below. 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 376°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test substance of 375°C.

Conclusions:
Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of EXP1200078.
The test substance is auto-ignitable with an auto-ignition temperature of 375°C at 983.2 - 1005.1 hPa.
Executive summary:

In a GLP study and in conformity with EC test guideline A.15, a commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of EXP1200078. The test substance is concluded to be auto-ignitable with an auto-ignition temperature of 375°C at 983.2 - 1005.1 hPa.
