Results and discussion

Relative self-ignition temperature (solids)
Key result
Relative self-ignition temperature:
> 188.8 °C
Remarks on result:
other: The sample temperature could not reach 400 °C prior to that of the oven, until the sample was heated to its melting point. Conclusion: the relative self-ignition temperature of the sample is above its melting point.
