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:
- 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Version / remarks:
- Published in O.J. L 142 (2008).
- Deviations:
- yes
- Remarks:
- The test substance was not dried as it contents high hydrophilic sulfonate salts that rapidly bind air humidity.
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Name: Saturn Grey LCGCAS: 31765-95-4Batch No.: 8010/2008Appearance: black powderStorage: dark dry room, closed container, at laboratory temperatureExpiration date: February 2018
- Contact with:
- powdered cellulose
- Key result
- Sample tested:
- test mixture as specified
- Remarks:
- 60 % w/w sample with cellulose
- Parameter:
- burning rate
- Remarks on result:
- mixture does not ignite and burn
- Sample tested:
- reference mixture as specified
- Remarks:
- 60 = barium nitrate with cellulose
- Parameter:
- burning rate
- Result:
- 0.81 mm/s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on results obtained from trial test, it is obvious that none of the test substance mixtures with cellulose burned all distance of 200 mm of the pile. Thus test substance, Direct Black 112, should not be considered as a substance with oxidizing properties.
- Executive summary:
The oxidizing properties of the test substance, Direct Black 112, were determined. The procedure was performed according to the method A.17 Oxidizing properties (Solids), Council Regulation (EC) Mo. 440/2008, published in O.J. L 142, 2008. Based on results obtained from trial test, it is obvious that none of the test substance mixtures with cellulose burned all distance of 200 mm of the pile. Thus test substance, Direct Black 112, should not be considered as a substance with oxidizing properties.

Description of key information
Based on results obtained from trial test, it is obvious that none of the test substance mixtures with cellulose burned all distance of 200 mm of the pile. Thus test substance, Direct Black 112, should not be considered as a substance with oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
