1 Scope This Standard specifies the gravimetric method or gas-volumetric method after combustion in the pipe furnace for the determination of non-combined carbon content. This Standard is applicable to the determination of non-combined carbon content with the content of 0.030 % (m/m)~ 5.00 % (m/m) in iron and carbon steel. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At time of publication, the editions indicated are valid. All standards are subject to revision, and parties using the standard shall investigate the possibility of applying the latest edition of the standards indicated below.
