Scope

This Part of GB/T 223 specifies a gas-volumetric method after combustion in the pipe
furnace for the determination of the carbon content.
This Part applies to the determination of the carbon content with the mass fraction of
0.10 % ~ 2.00 % in steel, iron, high temperature alloys and precision alloys.
