Application Summary AI generated

This standard specifies two methods for determining iron content in manganese metal, ferromanganese-silicon, ferromanganese, and nitrogen-bearing ferromanganese. It is applied in the metallurgical industry for quality control and chemical analysis of these manganese-based alloys and metals. The ortho-phenanthroline spectrophotometric method is used for low iron content, while the titanium trichloride-potassium dichromate titrimetric method is used for higher iron content.
