Executive summary:

The susbstance was tested for oxidizing properties according to EU A.17.

In the prelininary test, three test mixtures with the test item and cellulose 2:1 burned for 28 s, 45 s and 35 s, respectively. The flames extinguished before the pile was completely consumed. Subsequently a glowing of the test item mixture for more than 10 minutes was observed. Three test mixtures with barium nitrate/cellulose 2:1 burned down completely in 57 s, 57 s and 58 s, respectively. Due to the results of the preliminary test the main test had to be performed.

In hte main test, four tests were performed for the reference mixture (barium nitrate and cellulose) with 50, 55, 60 and 70 wt. % oxidizer (barium nitrate). The highest burning rate of 1.46 mm/s was found for the mixture with 55 wt. % oxidizer.

Mixtures of the test item with cellulose were prepared in between 10 and 90 wt. % of the test item and tested.

Due to the fact that the maximum burning rate of the mixtures of the test item with cellulose is lower than the maximum burning rate of the reference mixture, six tests were performed only with the three mixtures with the highest burning rates of 10, 20 and 30 wt.% of test item to verify these values.

The maximum burning rate of the mixtures of the test item and cellulose (0.98 mm/s) was lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.46 mm/s).

Due to the fact that the mixture of the test item with cellulose burned slower compared to the reference mixture it was concluded that the test item had no oxidizing properties.
