Results and discussion
Relative self-ignition temperature (solids)
- Remarks on result:
- no self ignition observed under the test conditions
- Remarks:
- No exothermic peaks have been observed in the heat flux plot. A small endothermic peak is observed between 130-150 °C, the latter is related to dehydration processes (as confirmed by the correspondent loss in weight visible in the thermogravimetric plot). The difference in temperature between the sample and the oven never exceeded 0.5 °C, the plots for the temperatures of the samples and of the oven are perfectly overlapping.
Applicant's summary and conclusion
- Conclusions:
- The analysis showed that no self-ignition processes are taking place when the sample is heated up to 450 °C in air flux
