Materials and methods
Test guideline
- Guideline:
- other: based on TG/DSC (Thermogravimetry/ differential scanning calorimetry) methods.
- Principles of method if other than guideline:
- The self-ignition properties are studied based on TG/DSC (Thermogravimetry/ differential scanning calorimetry) methods.

- no
- Remarks:
- other qulaity assurance
Test material
- Reference substance name:
- Iron silicate, copper smelting and refining
- EC Number:
- 701-480-0
- Cas Number:
- 67711-92-6
- IUPAC Name:
- Iron silicate, copper smelting and refining
- Details on test material:
- Two samples were tested:
Type I: Slag, Granules, Primary ( Sample 09TT02641)
Type III: Slag, Slow cooled, primary ( Sample 09TT05244)
Sampling and sample preparation was performed according to ECI/REACH C1 Sampling Protocol. The C1 sampling protocol also provides detailed information on the identity of the samples (see IUCLID section 1.4).

Results and discussion
Relative self-ignition temperature (solids)
- Remarks on result:
- no self-ignition observed up to the melting point
- Remarks:
- The first endothermic peaks appear at 1341oC (sample 09TT02641) and1027-1043oC (sample 09TT05244) when material starts to melt. Based on TG/DSC the studied material has no self-ignition properties
Any other information on results incl. tables
The first endothermic peaks appear at 1341oC (sample 09TT02641) and1027-1043oC (sample 09TT05244) when material starts to melt.
Based on TG/DSC the studied material has no self-ignition properties
Applicant's summary and conclusion
- Conclusions:
- The study is of good quality and demonstrates that the substance has not self-ignition properties.
- Executive summary:
TG/DSC measurements show that the substance remains stable upon heating up to 1027 – 1341 °C. On that basis and consideration of mineralogical composition it is evident that substance has not self-ignition properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
