Key result

Remarks on result:

no self ignition observed under the test conditions

The temperature of the solid test item and the temperature of the reference substance (graphite) do not differ until approx. 160 °C. At this point a slightly endothermic peak was observed followed by a larger endothermic event. Around 260 °C a very low exothermic event was recorded. Additional heating until 359 °C did not lead to a difference in the temperature profile of the test item and the reference substance.

No self-ignition test was performed with the test item. However, self-ignition of a solid can be excluded, if in the course of the Grewer oven test there is no temperature excursion of the sample of more than 400 °C (in relation to the reference sample). Based on data from the Grewer oven test the maximum observed temperature of the test item was 359 °C (no difference to the reference sample), which is quite below 400 °C. Therefore, the test item does not have any self-ignition properties.

Conclusions:

The test item does not have any self-ignition properties.

Executive summary:

The temperature of the solid test item and the temperature of the reference substance (graphite) do not differ until approx. 160 °C. At this point a slightly endothermic peak was observed followed by a larger endothermic event. Around 260 °C a very low exothermic event was recorded. Additional heating until 359 °C did not lead to a difference in the temperature profile of the test item and the reference substance. It can therefore be concluded, that the test-item does not have any self-ignition properties.
