Any other information on results incl. tables

The substance has shown to be thermally stable in presence of oxygen.

The mineralogical composition and particle size does not support the flammable properties of studied material.

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.
