Conclusions:
Tellurium dioxide had no oxidizing properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.17.
Executive summary:

The maximum burning rate of the mixtures of the test item and cellulose (1.38 mm/s) was lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (2.04 mm/s). Due to the fact that the mixture of the test item with cellulose burned slower compared to the reference mixture, or the flame extinguished before the pre-burning phase was finished, it was concluded that the test item has no oxidizing properties.

Tellurium dioxide had no oxidizing properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.17

Additional information

The maximum burning rate of the mixtures of the test item and cellulose (1.38 mm/s) was lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (2.04 mm/s). Due to the fact that the mixture of the test item with cellulose burned slower compared to the reference mixture, or the flame extinguished before the pre-burning phase was finished, it was concluded that the test item has no oxidizing properties.

Justification for classification or non-classification

Tellurium dioxide had no oxidizing properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.17
