GB/T 5686.5-2023: Ferromanganese, ferromanganese-silicon, nitrogen-bearing ferromanganese and manganese metal - Determination of carbon content - The Infrared absorption method, the gasometric method, the gravimetric method and the coulometric method
This document describes the determination of carbon content in ferromanganese, ferromanganese-silicon, nitrogen-bearing ferromanganese and manganese metal by the infrared absorption method, the gasometric method, the gravimetric method and the coulometric method. This document is applicable to the determination of carbon content in ferromanganese, ferromanganese-silicon, nitrogen-bearing ferromanganese and manganese metal. Determination range (mass fraction). 0.010% ~ 10.00% for method 1; 0.40% ~ 5.00% for method 2, not applicable to the determination of carbon content in nitrogen-bearing ferromanganese and manganese metal; 4.00% ~ 8.00% for method 3, applicable to the determination of carbon content in high carbon ferromanganese; 0.010% ~ 0.40% for method 4, only applicable to the determination of carbon content in manganese metal.
