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

The test item was observed as black pellets. Whilst heating the test item, no relevant exothermic reaction /self-heating of the sample has been observed. On completion of the test, the test item was observed as black pellets

Conclusions:
The test item has been determined to not have a relative self-ignition temperature below 400 °C
Executive summary:

No relative self-ignition below 400 °C using a procedure designed to be compatible with Method A.16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.
