Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-08
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Deviations:
- no
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- For testing the sample was grounded with a ball mill, thus the contact between the test item and the cellulose was maximised ("worst-case").
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- > 180 s
- Sample tested:
- 4:1 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:
- > 133.1 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- On the basis of the test results and according to the criteria specified in the CLP-/ GHS Regulation the substance "Ferromolybdenum Slags" (II23/030810/01) is not an oxidising solid.
Reference
On the basis of the test results and according to the criteria specified in the UN Recommendation on the Transport of Dangerous Goods, Manual of Tests and Criteria, the substance "Ferromolybdenum Slags" (II23/030810/01) does not met the criteria of Class 5.1, because the mean burning times of the 4:1 and 1:1 sample-to-cellulose ratio (by mass) are greater than the mean burning time of the 3:7 mixture (by mass) of potassium bromate and cellulose.
On the basis of the test results and according to the criteria specified in the CLP-/ GHS Regulation the substance "Ferromolybdenum Slags" (II23/030810/01) is not an oxidising solid.
Based on the experience of BAM with similar substances the substance "Ferromolybdenum Slags" (II23/030810/01) is also not an oxidising solid in the sense of the test method A.17 "OXIDISING PROPERTIES (SOLIDS)", COUNCIL REGULATIONS (EC) No.: 440/2008
Description of key information
Experimental study available with a representative sample (according to Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part 34.4.1, Test O.1: Test for oxidizing solids). Ferromolybdenum Slags are not oxidising solids in the sense of the classification criteria of the CLP Regulation.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
