- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Version / remarks:
- December 1992
- Deviations:
- no

- Key result
- Relative self-ignition temperature:
- 250 °C
- Remarks on result:
- other: The first exothermic reaction started at about 241 °C. The second exothermic heat effect started at about 373 °C.
- Conclusions:
- In conclusion, the test substance (EC: 433-100-1) is not auto-flammable.
- Executive summary:
The determination of the relative self-ignition temperature of the test substance was performed according to the EU method A.16. Using a linear increase in temperature of 0.5 K/min, the test substance (EC: 433-100-1) shows three exothermic reactions. The first exothermic reaction started at about 241 °C. The self-ignition temperature of the test substance (EC: 433-100-1) was determined to be 250 °C. A maximum temperature of about 498 °C was measured in the sample cube. The second exothermic heat effect started at about 373 °C. A maximum temperature of about 552 °C was measured in the sample cube. At the end of the run, the test substance (EC: 433-100-1) showed a loss of mass of about 82 % and coloured grey. In conclusion, the test substance (EC: 433-100-1) is not auto-flammable.
