Key result
Remarks on result:
no self ignition observed under the test conditions

4.34 g of the test item were filled into the stainless steel wire mesh cube and placed in the oven at 21°C. The test item showed a minor exothermat effect in the temperature range 155-190 °C which caused no significant temperature rise. Afterwards two endothermal effects were observed in the temperature ranges of 200 -210 °C and 215 - 230 °C (possibly another weak exothermal effect was located between these endothermal effects).

No further endothermal or exothermal effects up to the final test temperature of 401°C.

Conclusions:
The self-ignition temperature of the test item was determined to be >401 °C.
Executive summary:

No self-ignition temperature was observed up to the maximum test temperature of 401 °C, according to the testing guideline for auto-flammability (solids - determination of relative self-ignition temperature) in the sense of the European Commission Regulation (EC) No.440/2008, Method A.16.

Description of key information

The self-ignition temperature of the test item was determined to > 401 °C.

Key value for chemical safety assessment
