Scope

This part specifies the infrared absorption method, gasometric method,
gravimetric method, coulometric method to determine the carbon content of
ferromanganese-silicon, ferromanganese, blast furnace ferromanganese,
nitrogen-bearing ferromanganese, manganese metal, electrolytic manganese
metal.
This part applies to the determination of carbon content in ferromanganese-
silicon, ferromanganese, blast furnace ferromanganese, nitrogen-bearing
ferromanganese, manganese metal, electrolytic manganese metal. The
infrared absorption method is suitable for the determination of the carbon
content (mass fraction) of 0.01% ~ 10.00% in ferromanganese-silicon,
ferromanganese (including blast furnace ferromanganese), nitrogen-bearing
ferromanganese, manganese metal; electrolytic manganese metal. The
gasometric method is suitable for the determination of the carbon content (mass
fraction) of 0.40% ~ 5.00% in ferromanganese-silicon and ferromanganese
(including blast furnace ferromanganese). The gravimetric method is applicable
to the determination of ferromanganese (including blast furnace
ferromanganese). The determination of the carbon content (mass fraction) of
4.00% ~ 8.00%. The coulometric method is suitable for the determination of the
carbon content (mass fraction) of 0.010% ~ 0.400% in manganese and
electrolytic manganese metal.
