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:
- other: Unpublished guideline experimental study, reliable without restriction
- Qualifier:
- according to guideline
- Guideline:
- other: UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Fifth Edition
- Qualifier:
- according to guideline
- Guideline:
- other: Regulation (EC) No 1272/2008 (CLP-/GHS-Regulation)
- GLP compliance:
- no
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: Could not be ignited with the gas burner (burning time 2 min) at the preliminary screening test
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Disodium tetrachloropalladate does not fulfil the criteria of Class 4.1 "Flammable Solids" of UN-TDG and the Hazard Class "Flammable solids" of the Regulation (EC) No 1272/2008 (GHS/CLP) because it could not be ignited at the preliminary screening test.
- Executive summary:
Disodium tetrachloropalladate was assessed for flammability following the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria fifth Edition (2009) and Regulation (EC) No 1272/2008 (CLP-/GHS-regulation). Disodium tetrachloropalladate does not fulfil the criteria of Class 4.1 "Flammable Solids" of UN-TDG and the Hazard Class "Flammable solids" of the Regulation (EC) No 1272/2008 (GHS/CLP) because it could not be ignited at the preliminary screening test. The study is an unpublished guideline study that is reliable with-out restriction.

Description of key information
Disodium tetrachloropalladate could not be ignited in the preliminary screening test.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Michael-Schulz (2015) study is an unpublished, guideline study considered reliable and suitable for use as the key study for this endpoint. Disodium tetrachloropalladate does not fulfil the criteria of Class 4.1 "Flammable solids" of the UN-TDG and the Hazard Class "Flammable solids" of the Regulation (EC) No 1272/2008 (GHS/CLP) because it could not be ignited at the preliminary screening test.
Justification for classification or non-classification
Based on results from a guideline flammability study,disodium tetrachloropalladate does not fulfil the criteria of Class 4.1 "Flammable solids" of the UN-TDG and the Hazard Class "Flammable solids" of the Regulation (EC) No 1272/2008 (GHS/CLP) because it could not be ignited at the preliminary screening test.
