Applicant's summary and conclusion

Conclusions:
No cool flames were observed. No ignition was noted at 600°C.
Executive summary:

The test covers the determination of hot and cool flame autoignition temperatures of a liquid chemical in air at atmospheric pressure in a uniformly heated vessel (EC 440/2008, Annex Part A, test A15).

As determined by this method, the Autoiginition temperature (AIT) is the lowest temperature at which the substance will produce hot flame ignition in air at atmospheric pressure without the aid of an external ignition source such as spark or flame. It is the lowest temperature to which a combustible mixture must be raised so that the rate of heat evolved by the exothermic oxidation reaction will exceed the rate at which heat is lost to the surroundings and cause ignition.

When tested according to this guideline, the AIT of the test substance was more than 600°C.
