Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: Appendix 6, of the United Nations Recommendations on the Transport of Dangerous goods, Manual of tests and criteria 5th revised edition
- Principles of method if other than guideline:
- According to the guidance given in Appendix 6 testing is required if the structure contains oxygen. The oxygen present is in the form of SiO2 and is therefore not easily available for oxidation, or in small amounts of CuO. THus the oxidising properties of the test item can be predicted negative.
- GLP compliance:
- yes (incl. QA statement)
Test material
- Reference substance name:
- Reaction mass of dicopper selenide and selenium
- EC Number:
- 914-287-3
- Molecular formula:
- Cu2Se and Se
- IUPAC Name:
- Reaction mass of dicopper selenide and selenium
- Test material form:
- solid: particulate/powder
- Remarks:
- migrated information: powder
- Details on test material:
- Representative sample from the LE and LR responsible for this registration.

Results and discussion
Any other information on results incl. tables
According to the guidance given in Appendix 6 testing is required if the structure contains oxygen. The oxygen present is in the form of SiO2 and is therefore not easily available for oxidation, or in small amounts of CuO. Thus the oxidising properties of the test item can be predicted negative. Therefore, the classification procedure for oxidising substances need not to be applied.
Applicant's summary and conclusion
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information
- Conclusions:
- According to the guidance given in Appendix 6 testing is required if the structure contains oxygen. The oxygen present is in the form of SiO2 and is therefore not easily available for oxidation, or in small amounts of CuO. Thus the oxidising properties of the test item can be predicted negative. Therefore, the classification procedure for oxidising substances need not to be applied.
- Executive summary:
According to the guidance given in Appendix 6 testing is required if the structure contains oxygen. The oxygen present is in the form of SiO2 and is therefore not easily available for oxidation, or in small amounts of CuO. Thus the oxidising properties of the test item can be predicted negative. Therefore, the classification procedure for oxidising substances need not to be applied.
