Results and discussion
Test results (Oxidising solids)
- Sample tested:
- test mixture as specified
- Parameter:
- burning time of reaction over a distance of 200 mm
- Remarks on result:
- mixture does not ignite and burn
Any other information on results incl. tables
Since the burning rate is closer to that of the reference substance
the test item could have oxidizing properties.
However, these results could be a false positive since the test item is not a highly flammable substance (as reported in this GLP study).
In order to investigate the possible false positive hypothesis, the tests with the mixture (C, D and E) were repeated using kieselguhr (diatomaceous earth) as an inert support instead of the combustible cellulose.
| Mixture | Burning time over 200 mm (sec) | |
| C | 30/70 | burning does not propagate |
| D | 40/60 | burning does not propagate |
| E | 50/50 | burning does not propagate |
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- From the obtained experimental data according to the A.17 method in Council Regulation (EC)
No 440/2008 of 30 May 2008, it can be concluded that the test item formulation sample doesn’t
show oxidizing properties.
