Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 13 Nov 2017 to 22 Mar 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Version / remarks:
- 2016
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Version / remarks:
- 2015
- GLP compliance:
- yes
- Specific details on test material used for the study:
- - Identification: TAOBN
- Purity: 99.9%
- Appearance: White to pale yellow crystals
- Batch: 677700 - Contact with:
- powdered cellulose
- Duration of test (contact time):
- > 180 s
- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 154 s
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The mean burning time of both test item mixtures was more than the mean burning time of the 3:7 (w/w) reference mixture. Based on the results obtained it was concluded that the test item has no oxidizing properties.
Reference
A test item is considered an oxidizing substance when the burning time of a mixture of the substance and cellulose in a 4:1 or 1:1 sample-to-cellulose ratio (by mass) is less than or equal to the mean burning time of a 3:7 reference mixture (by mass) of potassium bromate and cellulose.
The mean burning time of the 3:7 reference mixture was 110 seconds.
Description of key information
The mean burning time of both test item mixtures was more than the mean burning time of the 3:7 (w/w) potassium bromate:cellulose reference mixture. Based on the results obtained it was concluded that the test item has no oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
The mean burning time of both test item mixtures was more than the mean burning time of the 3:7 (w/w) potassium bromate:cellulose reference mixture. Based on the results obtained it was concluded that the test item has no oxidizing properties. Therefore, the test item does not meet the criteria for CLP EC 1272/2008 classification as an oxidizing solid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
