GB/T 223.74-1991 Methods for chemical analysis of iron,steel and alloy--The combustion gravimetric/gasometric method for the determination of non-combined carbon content (English Version)
This standard specifies the determination of non-combined carbon by the combustion gravimetric method or the combustion gas volumetric method. This standard applies to the determination of the amount of non-combined carbon in iron and carbon steel. Measuring range: 0.030% to 5.00%.
