Results
1. Residual moisture
The test item contains a residual moisture of 0.1 wt%, which was determined by drying the test item under vacuum.
The reference item potassium bromate contains a residual moisture of < 0.1 wt%, which was determined by drying the test item under vacuum. The reference item cellulose contains a residual moisture of 4.0 wt%, which was determined by drying the test item under vacuum.
2. Oxidizing properties
The results of the reference mixtures of Potassium bromate and Cellulose are shown in Table 2:

The mean burning times of the test item-to-Cellulose ratio 4:1 (139 s) and 1:1 (205 s) are higher than the mean burning times of a 3:7 and 2:3 mixture of Potassium bromate and Cellulose (113 s or 55 s, respectively).
The test item in the 4:1 or 1:1 test item-to-Cellulose ratio exhibits a mean burning time greater than the mean burning time of a 3:7 mixture of Potassium bromate and Cellulose.
Applicant's summary and conclusion
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information UN-Transport Regulations / GHS
- Conclusions:
- The test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN-Transport Regulations.
The test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP-Guideline) Annex 1: 2.14. - Executive summary:
It was tested whether the test item should be assigned as oxidizing solid with respect to UN-Transport Regulations (Division 5.1) and GHS or EC 1272/2008 (CLP-Guideline) Annex 1:2.14, respectively.
Result: The test item in the 4:1 or 1:1 test item-to-Cellulose ratio exhibits a mean burning time greater than the mean burning time of a 3:7 reference mixture of Potassium bromate and Cellulose.
The test item is not an oxidizing solid.
