- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Version / remarks:
- 2015
- Deviations:
- no
- GLP compliance:
- yes
- Specific details on test material used for the study:
- Batch No.: 190722
Purity: > 99 wt% - Contact with:
- powdered cellulose
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Remarks on result:
- mixture does not ignite and burn
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 143 s
- Interpretation of results:
- other: not oxidizing
- Conclusions:
- The test item has no oxidizing properties and is therefore not classified as a Division 5.1 substance.
- Executive summary:
The full test was performed to monitor the oxidizing properties of test item based on UN Test O.1.
Based on the results obtained it was concluded that the test item has no oxidizing properties and is therefore not classified as a Division 5.1 substance.
Reference
The mean burning time of both test item mixtures was more than the mean burning time of the 3:7 (w/w) reference mixture. According to this, the test item has no oxidizing properties.
Description of key information
The full test was performed to monitor the oxidizing properties of test item based on UN Test O.1.
Based on the results obtained it was concluded that the test item has no oxidizing properties and is therefore not classified as a Division 5.1 substance.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
Data: UN Test O.1., The mean burning time of both test item mixtures (4:1, 1:1 (w/w) sample-to-cellulose ratio) was more than the mean burning time of the 3:7 (w/w) reference mixture.
In accordance with Regulation (EC) No. 1272/2008 Table 2.14.1, the substance should not be classified for the endpoint of oxidising solids.
