Preliminary test

The estimated auto-ignition temperature was 570 °C.

 

Main study

Ignition of the test material 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 material occurred was 562 °C. This temperature was rounded off to the nearest multiple of 5 °C giving an auto-ignition temperature of the test material of 560 °C.
