Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid having a melting point <= 160°C
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- according to guideline
- Guideline:
- other: A preliminary melting point assessment using differential scanning calorimetry was conducted and based on the results of this a full UN N4 test was not conducted.
- Deviations:
- not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks on result:
- other: No testing was performed using Test N.4 of the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, fifth revised edition 2009 as the melting temperature of test item was assessed to be less than 160 °C.
- Conclusions:
- No testing was performed using Test N.4 of the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, fifth revised edition 2009 as the melting temperature of rhodium (III) nitrate hydrate was assessed to be less than 160 °C using Differential Scanning Calorimetry.
- Executive summary:
No testing was performed using Test N.4 of the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, fifth revised edition 2009 as the melting temperature of rhodium (III) nitrate hydrate was assessed to be less than 160 °C using Differential Scanning Calorimetry in a preliminary assessment (Atwal and Tremain 2011).

No testing was performed using Test N.4 of the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, fifth revised edition 2009 as the melting temperature of rhodium (III) nitrate hydrate was assessed to be less than 160 °C using Differential Scanning Calorimetry (DSC).
Description of key information
In accordance with column 2 of REACH Annex VII, the self-ignition temperature study does not need to be conducted as the substance is a solid with a melting point less than 160°C. The melting temperature of rhodium (III) nitrate hydrate was assessed to be less than 160°C using Differential Scanning Calorimetry.

Additional information
No testing was performed using Test N.4 of the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, fifth revised edition 2009 as the melting temperature of rhodium (III) nitrate hydrate was assessed to be less than 160°C using Differential Scanning Calorimetry in a preliminary assessment (Atwal and Tremain 2011).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
