Key result
Sample tested:
other: 10, 30, 60 and 80% w/w mixture of test substance and cellulose
Parameter:
burning time of reaction over a distance of 200 mm
Remarks on result:
other: The test substance attenuates the burning characteristics of cellulose
Interpretation of results:
GHS criteria not met
Conclusions:
Not an oxidising substance.
Executive summary:

The test substance is not classified as an oxidising substance, when tested according to EU method A.17.

The test substance was mixed with a defined combustible substance (cellulose) in ratios of 10, 30, 60, and 80% w/w and the burning rate of a train of each mixture was determined. The maximum burning rate was compared with the maximum burning rate of a reference mixture (100% cellulose and 60% w/w barium nitrate/cellulose).

In each of the ratios tested, the sample ignited and propagated combustion by burning with a flame along the full length of the train. However, the burning rate was lower than the burning rate of the reference mixtures and decreased as the proportion of test substance in the mixture was increased. The test substance clearly attenuates the burning characteristics of cellulose.
