GB/T 5686.5-2008 《Ferromanganese, ferromanganese-silicon , nitrogen-bearing ferromanganese and manganese metal - Determination of carbon content - The infrared absorption method ,the gasometric method ,the gravimetric and the coulometric method》 Related products

This part specifies the test methods for the determination of carbon content of manganese-silicon alloys, ferromanganese, blast furnace ferromanganese, ferromanganese nitride, metallic manganese and electrolysis metallic manganese by infrared absorption method, gas volumetric method, weight method and Coulometry. Different methods are suitable for the determination of different carbon content ranges and are used for the quality control of manganese alloys and metallic manganese in industrial production.
