The tests with the mixtures potassium bromate:cellulose 2:3 and 3:2 were not performed, because the burning time of the mixtures of the test item with cellulose was higher than the burning time of the reference mixture 3:7.

The results of the mixtures of test item and cellulose are shown in Table 2:

The burning time of the mixtures of the test item with cellulose (4:1 and 1:1) is greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Due to the tests the test item does not have to be classified as oxidizing solid.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The burning time of the mixtures of the test item Leuco Sulfur Blue 15 with cellulose (4:1 and 1:1) was greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Based on the test results the test item does not have to be classified as oxidizing solid.

In accordance with the results obtained in UN Test O.1 (Oxidising Properties, Solids) the test item is classified as follows:
UN Transport Regulation: The test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation.
GHS and EC 1272/2008 (CLP Regulation), Annex 1: 2.14: The test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.14.
