Reference
Preliminary Test
-The estimated auto-ignition temperature was 245 °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 < 10 °C. According to the guidelines, no further testing was required.
- The lowest temperature at which ignition of the test material occurred was 239 °C. This temperature was rounded down to the nearest multiple of 5 °C giving an auto-ignition temperature of the test material of 235 °C.
