Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The cone-shaped pile formed during the Preliminary Test could not be ignited therefore the Main Test was performed.
The maximum burning rate of the test item in different mixtures was found to be lower than the burning rate of the reference mixture in the Main Test. C.I. Leuco Sulfur Green 2 is not considered as an oxidizing substance.
Executive summary:

The purpose of this study was to investigate the oxidizing properties of the test item.

The maximum burning rate of the test item in different mixtures was found to be lower than the burning rate of the reference mixture in the Main Test. C.I. Leuco Sulfur Green 2 is not considered as an oxidizing substance.
