Key result
Relative self-ignition temperature:
> 400 °C
Remarks on result:
no self ignition observed under the test conditions
Conclusions:
The test item has been determined to not have a relative self-ignition temperature below 400 °C.
Executive summary:

The auto flammability of the test item was determined 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, in accordance with GLP.

Whilst heating the test item, no relevant exothermic reaction /self-heating of the sample was observed. On completion of the test, the test item was an expanded black, charred mass.

The test item has been determined to not have a relative self-ignition temperature below 400 °C.
