Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Interpretation of results:
- non flammable
- Conclusions:
- Dirhodium trioxide is not classified as a readily combustible solid in accordance with Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures as it failed to ignite in the preliminary screening test.
- Executive summary:
Tremain and Atwal (2011) is a GLP compliant study following UN method N1 and is considered suitable for use for assessment of this endpoint. Dirhodium trioxide is not classified as a readily combustible solid in accordance with Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures as it failed to ignite in the preliminary screening test
Reference
Description of key information
A preliminary careening test has been conducted and dirhodium trioxide is not classified as a readily combustible solid as it failed to ignite in the preliminary screening test.
In addition, the flammability test is not scientifically justifiable as this substance is a stable oxide and/or is in its highest oxidation state.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Tremain and Atwal (2011) is a GLP compliant study following UN method N1 and is considered suitable for use for assessment of this endpoint. Dirhodium trioxide is not classified as a readily combustible solid in accordance with Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures as it failed to ignite in the preliminary screening test
Justification for classification or non-classification
Dirhodium trioxide is not classified as a readily combustible solid in accordance with Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures as it failed to ignite in the preliminary screening test
