- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 3 min
- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Remarks on result:
- mixture does not ignite and burn
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Remarks on result:
- mixture does not ignite and burn
- Key result
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 125 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The burning time of the mixtures of the test item TA-2 with cellulose (4:1 and 1:1) was higher than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Due to the tests results the test item does not have to be classified as oxidizing solid.
The test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation.
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.

The tests with the mixture 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 mixtures 3:7. Due to this result the test item does not have to be classified as oxidizing solid.
Description of key information
The burning time of the mixtures of the test item TA-2 with cellulose (4:1 and 1:1) was higher than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Due to the tests results the test item does not have to be classified as oxidizing solid.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
The test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation.
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.
