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:
- 15.07.-21.07.2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Deviations:
- yes
- Remarks:
- Based on earlier studies the test substance was not dried. The reason is that the test substance contents high hydrophilic sulfonate salts that rapidly bind air humidity. This deviation has no negative impact on the study results.
- GLP compliance:
- yes (incl. QA statement)
- Contact with:
- other: powdered cellulose, barium nitrate
- Duration of test (contact time):
- > 10 - < 430 s
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- preliminary test
- Result:
- 20 s
- Remarks on result:
- mixture does not ignite and burn
- Sample tested:
- reference mixture as specified
- Remarks:
- barium nitrate 60% and 40% cellulose
- Parameter:
- mean burning time
- Result:
- > 0.61 - < 0.81 mm/s
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- preliminary test
- Remarks on result:
- mixture does not ignite and burn
- 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 Blue 78, shouldn´t be considered as a substance with oxidizing properties.
- Executive summary:
The oxidizing properties of test substance, Direct Blue 78, were determined.
The procedure was performed according to the Method A.17 Oxidizing properties (Solids),Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008.
