Reference
Preliminary test:
The estimated auto-ignition temperature was 285°C.
Main test:
The results of the main study on the determination of the auto-ignition temperature of the test substance is given in Table 1.
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.
The lowest temperature at which ignition of the test substance occurred was 275°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test substance.
