Specific details on test material used for the study:
Identification: Reaction mass of crystalline magnesium silicate and crystalline silicon and synthetic amorphous silicon dioxide
Appearance/Physical state: Black powder
Batch: Y180510A
Purity: 95 min wt%
Expiry date: 31 May 2019
Storage conditions: Room temperature in the dark
Key result
Relative self-ignition temperature:
> 400 °C
Remarks on result:
no self ignition observed under the test conditions

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

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

Relative Self-Ignition Temperature for Solids. 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.
