Applicant's summary and conclusion

Conclusions:
Based on the test phenomena and results, the sample temperature could not reach 400℃ until
it was heated to its melting point. There was no substance in the vessel after the test completed.
The sample temperature could not reach 400℃ prior to that of the oven. The relative
self-ignition temperature of the sample was not detected.
