Preliminary test:
Two test mixtures with the test item and cellulose 2:1 burned down completely in 175 and 270 s.
Three tests mixtures with barium nitrate/cellulose 2:1 burned down completely in 85, 87 and 86 s. Also the inner material of the cone burned down completely.
Due to the results of the preliminary test the full test had to be performed.
Main test:
Five tests were performed for the reference mixture with 40, 50, 55, 60 and 70 percent oxidizer.The results are shown in the following table.
Barium nitrate [%] | Burning time over 200 mm [s] | Burning rate [mm/s] |
40 | 236 | 0.85 |
50 | 233 | 0.86 |
55 | 182 | 1.10 |
60 | 231 | 0.87 |
70 | 307 | 0.65 |
The highest burning rate 1.10 mm/s was found for the mixture with 55% oxidizer.
Mixtures of the test item with cellulose were prepared in 10%-increments between 10 and 50 wt.%test item and tested. Higher concentrations of test item were not used due to the fact that already for a concentration between 20 and 50 wt.% of test item the mixture burned slower. Additional tests with 2.5, 5, 15 and 100 wt.% test item were performed.
The following table shows the results.
Test item [%] | Burning time over 200 mm [s] | Burning rate [mm/s] |
2.5 | 206 | 0.97 |
5 | 208 | 0.96 |
10 | 202 | 0.99 |
15 | 206 | 0.97 |
20 | 285 | 0.70 |
30 | 278 | 0.72 |
40 | 410 | 0.49 |
50 | 445 | 0.45 |
60, 70, 80, 90 | Due to the fact that the mixture between 20 and 50 % of test item burned slower, no tests were performed for these mixtures

Six tests were performed for the mixtures with the highest burning rates of 5, 10 and 15 wt.% of test item.

The maximum burning rate of the mixtures of the test item and cellulose (1.05 mm/s) was less than (nearly as high as) the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.10 mm/s). Additional experiments of test item with Kieselguhr and of barium nitrate (55 wt.%) with kieselguhr were performed due to the fact, that the burning rates were nearly the same.
The following table shows the results.
Test item [%] | Burning time over 200 mm | Burning rate [mm/s] |
10 | The test item could not be ignited with a flame, no reaction was observed | - |
20 | The test item could not be ignited with a flame, no reaction was observed | - |
40 | The flame extinguish after 5 s, no propagation | - |
60 | The flame extinguish after 15 s, no propagation | - |
70 | 330 | 0.61 |
100 | The test item could not be ignited with a flame the test item melted. | - |
Barium nitrate [%] | Burning time over 200 mm [s] | Burning rate [mm/s] |
55 | The test item could not be ignited with a flame, no reaction was observed | - |
For the pure test item the test item melted when a flame was applied as ignition source. The melt did not burn due to the limited surface of the melt.
A mixture of 70 wt.% of test item with Kieselguhr showed a propagating combustion. For lower concentrations of test item only a local combustion was observed. Due to the fact that Kieselguhr is an inert substance and does not burn it has to be concluded from this test, that the melted test item sustained the combustion if soaked in a porous material. In mixture with Kieselguhr the melted test item was soaked in the porous Kieselguhr and led to an increase of the free surface, which sustained the combustion.
From these tests it can be concluded that also in mixture with cellulose the melted test item was soaked in the porous structure of the cellulose and sustained the combustion. The burning rate of the mixtures of test item with cellulose which was nearly equal to the burning rate of the reference mixtures of barium nitrate with cellulose was not caused by oxidizing properties of the test item but by the combustibility of the melted test item in the porous materials cellulose or Kieselguhr.
Due to the burning behaviour of the mixture of test item with Kieselguhr, it is concluded, that the test item has no oxidizing properties.

Additional information
The substance has no oxidising properties (EU Method A.17, contact with cellulose)
Justification for classification or non-classification
The available data on oxidising properties of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification: The organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen. Also the substance is found with no oxidising propoerties according to EU Test Method A.17.
