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 252 °C. This temperature was rounded down to the nearest multiple of 5 °C giving an auto-ignition temperature of the test item of 250 °C.

Applicant's summary and conclusion

Conclusions:
The test item has an auto-ignition temperature of 250 °C.
Executive summary:

The auto flammability of the test item was measured according to EC Method A.15, DIN 51794. The test item was deteremined to have an auto-ignition temperature of 250 °C.
