Reference
The maximum burning rate of the mixtures of the test item and cellulose (0.68 mm/s) was slower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.01 mm/s). Due to these results, the test item has no oxidizing properties.
Individual Results
Preliminary test
Three tests mixtures with the test item and cellulose 2:1 burned did not burned down completely. The
flame extinguished after a period of 118, 38 and 123 s. The flame burned only on the surface.
Three tests mixtures with barium nitrate/cellulose 2:1 burned down completely in 82, 85 and 81 s.
Therefore the full test was necessary, because the test item burned down not completely.
Five tests were performed for the reference mixture (Barium nitrate and Cellulose) with 40, 50, 55, 60
and 70 wt.% oxidizer (barium nitrate). The results are shown in the following table.

- non oxidising
Additional information
EU Method A.17
The maximum burning rate of the mixtures of the test item and cellulose (0.68 mm/s) was slower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.01 mm/s). Due to these results, the test item has no oxidising properties.
Justification for classification or non-classification
No classification, the substance is non oxidising.
Justification: The maximum burning rate of the mixtures of the test item and cellulose (0.68 mm/s) was slower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.01 mm/s). Due to these results, the test item has no oxidising properties according to regulation 67/548/EEC Annex V.
The substance is incapable of reacting exothermically with combustible materials on the basis of the chemical structure (regulation 1272/2008; CLP).
