Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:

- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Version / remarks:
- OJ No. L383A, 29.12.92
- Deviations:
- no
- GLP compliance:
- yes
- Specific details on test material used for the study:
- Batch No.: 960509
Purity: 92.3% - Contact with:
- powdered cellulose
- Sample tested:
- test mixture as specified
- Remarks:
- 70% test substance
- Parameter:
- burning time of reaction over a distance of 200 mm
- Result:
- 200 s
- Sample tested:
- reference mixture as specified
- Remarks:
- 60% barium nitrate/cellulose mixture
- Parameter:
- burning time of reaction over a distance of 200 mm
- Result:
- 81 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item is not oxidising.
- Executive summary:
Oxidising properties was determined determines using the methods compared to a reference oxidising substance Barium nitrate as described in EC A 17.
The fastest burning 60% barium nitrate/cellulose mixture had a burning time of 76 s whereas the fastest burning test substance/cellulose mixture from the extended test was 193 s for a mixture containing 70% test substance.
As none of the test mixtures burned more rapidly than the barium nitrate reference mixtures, the test item is not oxidising.
Reference
- Preliminary results:
The pile containing the most cellulose burnt most strongly, but as the reaction could not be described as vigorous the full train test was required.
Description of key information
Oxidising properties was determined determines using the methods compared to a reference oxidising substance Barium nitrate as described in EC A 17.
The fastest burning 60% barium nitrate/cellulose mixture had a burning time of 76 s whereas the fastest burning test substance/cellulose mixture from the extended test was 193 s for a mixture containing 70% test substance.
As none of the test mixtures burned more rapidly than the barium nitrate reference mixtures, the test item is not oxidising.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
Oxidising properties: EC A17, non oxidising
The fastest burning 60% barium nitrate/cellulose mixture had a burning time of 76 s whereas the fastest burning test substance/cellulose mixture from the extended test was 193 s for a mixture containing 70% test substance.
In accordance with Regulation (EC) No. 1272/2008 section 2.14.2., the substance should not be classified as oxidising solid.
