Results and discussion

Relative self-ignition temperature (solids)
Key result
Relative self-ignition temperature:
ca. 392 °C

Applicant's summary and conclusion

Conclusions:
Relative self-ignition was recorded as 392°C by the apparatus as the sample reached 400°C when the oven temperature was 392°C. However it should be added that the substance self-ignites from 212.7°C but without reaching 400°C.
