Applicant's summary and conclusion
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information
- Conclusions:
- The test item had no oxidizing properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.17.
- Executive summary:
The substance was tested for oxidizing properties according to European Commission Regulation (EC) No. 440/2008, A.17. Oxidizing properties of solids.
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 1.61 mm/s was found for the mixture with 60 wt. % oxidizer.
Mixtures of the test item with cellulose were prepared in between 10 and 70 wt. % of the test item and were tested.
The maximum burning rate of the mixtures of the test item and cellulose (1.65 mm/s) was higher than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.61 mm/s) . Therefore the additional tests with kieselguhr and under an inert atmosphere had to be performed.
The mixture of test item (50 %) with Kieselgur showed no propagating combustion. Due to this result a further test under inert atmosphere was necessary.
A mixture of the test item with cellulose was prepared using 50 % of the test item. A mixture of barium nitrate with cellulose was prepared using 60 wt.% of barium nitrate. The mixtures were tested under argon atmosphere.
The mixture of cellulose and test item could not be ignited, only decomposition was oberserved. The mixture of barium nitrate and cellulose showed a burning rate of 0.99 mm/s.
Due to the results of the experiments in an inert atmosphere, it can be stated that the test item had no oxidizing properties.
