Since the maximum burning rate of the mixtures tested (1.49 mm/s) is lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.92 mm/s) and no vigorous reaction was observed in the preliminary test, the tested material is regarded as not oxidising.

Interpretation of results:

GHS criteria not met

Conclusions:

The tested material has not oxidizing properties in accordance with test A.17 criteria.

Executive summary:

The study of determination of oxidizing properties of solids was performed according to method A.17 Oxidizing properties for solids, following the principles of GLP. The test was performed with the reference substance and at least once with each one of the range of mixtures of the test substance with cellulose. The maximal burning rate of the reference mixture train was 1.92 whereas the maximal burning rate of the train for the test item was 1.49. The maximum burning rate of the mixtures tested is lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate and no vigorous reaction was observed in the preliminary test. Concluding, the tested material has not oxidizing properties.
