Any other information on results incl. tables

The substance has shown to be thermally stable in presence of oxygen. Based on TG/DSC measurements the oxidation starts at 630oC. (sample 09TT02641) and~800 °C (sample 09TT05244).

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The study indicates that the copper slag has no flammability
properties
Executive summary:

The substance has shown to be thermally stable in presence of oxygen up to 630oC. and over.

The TG/DSC measurements and mineralogical composition does not support the flammable properties of copper slag.
