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
Abstract
This document describes the methods for determining the carbon content in ferromanganese, manganese-silicon alloys, manganese nitrides, and metallic manganese using infrared absorption, gas volume, weight, and Coulomb methods. This document is applicable to the determination of carbon content in ferromanganese, manganese-silicon alloys, manganese nitrides, and metallic manganese. The measurement range (mass fraction): Method I is 0.010% to 10.00%; Method II is 0.40% to 5.00%, not applicable to the determination of carbon content in manganese nitrides and metallic manganese; Method III is 4.00% to 8.00%, applicable to the determination of carbon content in high-carbon ferromanganese; Method IV is 0.010% to 0.40%, only applicable to the determination of carbon content in metallic manganese.
