Observations

All reference substance mixtures showed clear signs of oxidising properties (cracks, sparkling).

All test substance mixture burned with orange soot emitting flame and carbonized.

The mixture with 20 % test substance IMEXINE OBA/50 SEC shows the highest burning rate.

The burning rate surpasses the burning rate of the reference mixture with the highest burning rate. Therefore the test substance mixture was operated under argon. The mixture did not ignite. Therefore, the study was terminated and the test substance was considered to have no oxidising properties.

Result

The mixture 20% test substance IMEXINE OBA/50 SEC showed a higher burning rate as the burning rate of the reference mixture. But the result was a false positive value. Therefore the test substance mixture was operated under argon. The mixture did not ignite. Therefore, the study was terminated and the test substance was considered to haveno oxidising properties.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The mixture 20% test substance IMEXINE OBA/50 SEC showed a higher burning rate as the burning rate of the reference mixture. But the result was a false positive value. There-fore the test substance mixture was operated under argon. The mixture did not ignite. Therefore, the study was terminated and the test substance was considered to have no oxidising properties.
Executive summary:

The oxidising properties of the test item (solid) was determined with a not-GLP compliant study, following the EU method A.17.

The mixture 20% test substance IMEXINE OBA/50 SEC showed a higher burning rate as the burning rate of the reference mixture. But the result was a false positive value, as the miwture did not ignite when the test was operated under argon. Therefore the test substance mixture was operated under argon. The mixture did not ignite. Therefore, the study was terminated and the test substance was considered to have no oxidising properties.
