Materials and methods

Principles of method if other than guideline:
The flamability properties are studied based on TG/DSC (Thermogravimetry/ differential scanning calorimetry) methods.
GLP compliance:
no
Remarks:
other quality assurance

Test material

Reference
Name:
Unnamed
Type:
Constituent
Details on test material:
Typical nickel slag sample ( 4683) representative for the production process was collected at the manufacturing site:

Sampling and sample preparation was performed according to ECI/REACH C2 Sampling Protocol. The C2 sampling protocol also provides detailed information on the identity of the samples (see IUCLID section 1.4).

Results and discussion

Any other information on results incl. tables

The first endothermic peaks appear at 1404oC 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 subsatnce 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.
