Results and discussion

Relative self-ignition temperature (solids)

Key result

Relative self-ignition temperature:

> 400 °C

Remarks on result:

no self-ignition observed up to the melting point

Applicant's summary and conclusion

Conclusions:

Heating the substance to >400 °C in air for determination of the melting point does not show auto flammability.
