WARNING: Personnel applying this standard should have practical experience in formal laboratory work. This section does not address all possible security issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This part specifies the determination of sulfur content in manganese-silicon alloy, ferromanganese, blast furnace ferromanganese, ferromanganese nitride, metallic manganese and electrolytic metallic manganese by infrared absorption method and combustion neutralization titration method. This section applies to the determination of sulfur content in manganese-silicon alloy, ferromanganese, blast furnace ferromanganese, ferromanganese nitride, metallic manganese and electrolytic metallic manganese. Among them, the infrared absorption method is suitable for the determination of 0.005% to 0.120% sulfur content (mass fraction) in manganese-silicon alloy, ferromanganese, blast furnace ferromanganese, ferromanganese nitride, metal manganese and electrolytic metal manganese; combustion neutralization titration method is suitable Determination of 0.015% to 0.120% sulfur content (mass fraction) in manganese-silicon alloy, ferromanganese (including blast furnace ferromanganese), manganese metal and electrolytic manganese metal.
