Applicant's summary and conclusion

Conclusions:
The test item showed a self-ignition reaction at 308 °C.
Executive summary:

Using a linear increase in temperature of 0.5 °C/min up to 410 °C, the test item Solvent Red 119 showed a sharp temperature rise above the oven temperature. The test was performed two times and the self-ignition temperature of the test item was: 309.3 °C (Test 1) and 308 °C (Test 2). At the end of measurement the test item was solid and the colour was brown-black.
