GB/T 5686.1-2022 《Ferromanganese，ferromanganese-silicon，nitrogen-bearing ferromanganese and manganese metal—Determination of manganese content—Potentiometric method， titrimetric method after ammonium nitrate oxidation and titrimetric method after perchloric acid oxidation》 Related products
This standard specifies the method for the determination of manganese content in ferromanganese, silicon manganese alloys, ferromanganese nitride and metallic manganese by the potentiometric Titrimetric method, the ammonium nitrate oxidation Titrimetric method and the perchloric acid oxidation Titrimetric method. The applicable manganese content range is 50.00% to 98.00%. The standard specifically states that this method is not suitable for the determination of manganese content when the chromium or vanadium content in the sample exceeds 0.4%. The document details the experimental operation method, reagent preparation and measurement procedure, and provides specifications for the analysis of manganese content in related materials.
