- mixture does not ignite and burn
- Remarks:
- Tested 5 times
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 255 s
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 111 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test results indicated that the test item is not an oxidizing solid under the conditions of the test.
Reference
The 4:1 did not ignite and 1:1 test item:cellulose mixtures exhibited mean burning time greater than that of the 3:7 potassium bromate to cellulose mixture This indicates that the test item is not an oxidizing solid.
Description of key information
The oxidizing properties of the test item were determined by comparing the burning characteristics of mixtures of test item and dry fibrous cellulose (in ratios of 1:1 and 4:1 by mass) with a mixture of potassium bromate and dry fibrous cellulose (in ratio of 3:7 by mass). Testing complied with Test O.1 specified in the United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria, fifth revised edition 2009 and Section 2.14 Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
The 4:1 did not ignite and 1:1 test item:cellulose mixtures exhibited mean burning time greater than that of the 3:7 potassium bromate to cellulose mixture This indicates that the test item is not an oxidizing solid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
