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:
- yes
- Remarks:
- Due to limited amount of test item available the pile was only 130mm long not 250mm as detailed in the method.
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: The pile failed to ignite during the 5 minutes that the Bunsen flame was applied.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Rhodium is not classified as a readily combustible solid under Division 4.1 as it failed to ignite in the preliminary screening test.
- Executive summary:
This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. Rhodium is not classified as a readily combustible solid under Division 4.1 as it failed to ignite in the preliminary screening test.

Description of key information
Rhodium is not classified as a readily combustible solid under Division 4.1 as it failed to ignite in the preliminary screening test.
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 as the key study for this endpoint. Rhodium is not classified as a readily combustible solid under Division 4.1 as it failed to ignite in the preliminary screening test.
Adinex N.V. (2000) follows EU method A10 and is suitable for use as a supporting study for this endpoint. As no ignition occurred after applying an ignition source (glowing Pt-wire of approximately 1000°C and flame of gas burner) no burning rate can be determined. Rhodium was determined to be non-flammable.
Justification for classification or non-classification
Rhodium is not classified as a readily combustible solid under Division 4.1 as it failed to ignite in the preliminary screening test.
