Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2014-12-22~2014-12-23
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The lab does not acquire a GLP certification
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Sample tested:
- reference mixture (not specified)
- Parameter:
- maximum burning rate
- Result:
- 1.47 mm/s
- Remarks on result:
- sparking
- Key result
- Sample tested:
- test mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- maximum burning rate
- Result:
- < 1.47 mm/s
- Remarks on result:
- mixture does not ignite and burn
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test result showed that the maximum burning rate of mixture of sample with cellulose is less than maximum burning rate of reference mixture 1.47mm/s.
- Executive summary:
According to EC REGULATION No 440/2008 Annex A.17 Oxidizing Properties (Solids), the sample is not considered as an oxidising substance. The test result is "no oxidising properties." Therefore, it is not classified under CLP.

Description of key information
The sample is not considered as an oxidizing substance.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
The result of preliminary test shows that the sample mixture burn very slowly, so the full train test is necessary. And the result of train test shows that, for sample cellulose-mixtures containing 10 to 90 % weight of sample, the piles can't be ignited in 2min. Test result showed that the maximum burning rate of mixture of sample with cellulose is less than maximum burning rate of reference mixture 1.47mm/s.
Justification for classification or non-classification
According to EC REGULATION No 440/2008 Annex A.17 Oxidizing Properties (Solids), the sample is not considered as an oxidizing substance. The test results are "no oxidising properties", so that hazard category in CLP is not classified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
