Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2016-06-30
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- GLP compliance:
- no
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: Substance did not ignite during the preliminary screening test.
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test substance did not ignite during the preliminary screening test. Based on this result, it should be considered as non-combustible.
- Executive summary:
The flammability of niobium dioxide was tested according to EU method A.10. In a preliminary test, the test substance was formed into a powder train about 250 mm long by 20 mm wide by 10 mm high on a fireclay plate. A hot flame from a gas burner was applied to one end of the powder train for five minutes. There was no ignition observed. Since the test substance did not ignite it should not be considered as highly flammable and no further testing is required.
The test substance niobium dioxide is therefore considered as non-combustible.
Reference
Since the test substance did not ignite during the preliminary screening test, it should not be considered as highly flammable and no further testing is required.
Description of key information
The test substance niobium dioxide (NbO2) is non-combustible.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The flammability of niobium dioxide was tested according to EU method A.10. In a preliminary test, the test substance was formed into a powder train about 250 mm long by 20 mm wide by 10 mm high on a fireclay plate. A hot flame from a gas burner was applied to one end of the powder train for five minutes. There was no ignition observed. Since the test substance did not ignite it should not be considered as highly flammable and no further testing is required.
The test substance niobium dioxide is therefore considered as non-combustible.
Justification for classification or non-classification
Since the test substance did not ignite in a preliminary test conducted in accordance with EU method A.10, it should not be considered as highly flammable and no further testing is required. The test substance niobium dioxide is therefore considered as non-combustible and no classification is warranted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
