Results and discussion

Test results (Oxidising solids)
Key result
Sample tested:
test mixture as specified
Remarks:
Oxidiser cellulose-mixtures containing 10 to 90 % weight of oxidiser in 10 % increments were prepared
Parameter:
burning time of reaction over a distance of 200 mm
Remarks on result:
mixture does not ignite and burn
Remarks:
Leuco Sulfur Red 14 is not considered as an oxidizing substance.

Any other information on results incl. tables

The cone-shaped pile formed during the Preliminary Test could not be ignited therefore the Main Test was performed. The maximum burning rate of the test item in different mixtures was found to be lower than the burning rate of the reference mixture in the Main Test. Leuco Sulfur Red 14 is not considered as an oxidizing substance.
