Scope

This part specifies the infrared absorption method and combustion-
neutralization method to determine the sulfur content in ferromanganese-silicon,
ferromanganese, blast furnace ferromanganese, nitrogen-bearing
ferromanganese, manganese metal, electrolytic manganese metal.
This part applies to the determination of sulfur in manganese-silicon alloy,
ferromanganese, blast furnace ferromanganese, nitrogen-bearing
ferromanganese, manganese metal, electrolytic manganese metal. The
infrared absorption method is suitable for the determination of sulfur content
(mass fraction) of 0.005% ~ 0.120% in manganese-silicon alloy,
ferromanganese, blast furnace ferromanganese, nitrogen-bearing
ferromanganese, manganese metal, electrolytic manganese metal. The
combustion-neutralization method is suitable for the determination of the sulfur
content (mass fraction) of 0.015% ~ 0.120% in manganese-silicon alloy,
ferromanganese (including blast furnace ferromanganese), manganese metal,
electrolytic manganese metal.
