Results and discussion

Relative self-ignition temperature (solids)
Relative self-ignition temperature:
364.13 °C

Any other information on results incl. tables

Figure 1 (see attached) shows the changes in oven temperature and sample temperature over time.

The sample tracks the oven temperature until 275.60°C where the sample enters a notable exothermic reaction to a maximum temperature of 545.32°C, reaching its self-ignition temperature at 364.13°C. On completion of testing a black solid remains.
