For each of the burning times quoted below, the test substance mixture ignited and burned with a flame, with combustion propagating fully along the train. The maximum overall burning rate is 1.5 mm/s for the 10% test substance mixture. The maximum burning rate of the test substance/cellulose mixtures falls well below the maximum burning rate of 2.8 mm/s for the 60 % barium nitrate/cellulose reference mixture.

Interpretation of results:

GHS criteria not met

Conclusions:

The maximum burning rate of the test substance (1.5 mm/s at 10 % test substance and 90 % cellulose) was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose, (2.8 mm/s at 60:40). The product is therefore not considered an oxidising substance.

Executive summary:

The oxidising potential of the test substance was determined according to EC Test A.17 following GLP principles. The maximum burning rate of the test substance (1.5 mm/s at 10 % test substance and 90 % cellulose) was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose, (2.8 mm/s at 60:40). The product is therefore not considered an oxidising substance.

Description of key information

Oxidising properties: The maximum burning rate of the test substance was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose. The product is therefore not considered an oxidising substance. EC Test A.17, Jackson 2008.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

Based on the available information, classification on oxidising properties is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
