This part of GB/T 223 specifies the determination of molybdenum by thiocyanate direct spectrophotometry and thiocyanate-butyl acetate extraction spectrophotometry. The method-1 of this part is applicable to the determination of molybdenum content of 0.10%~2.00% (mass fraction) in medium-and-low alloy steel, hightemperature alloy steel, precision alloy. The method-2 of this part is applicable to the determination of molybdenum content of 0.0025% ~ 0.20% (mass fraction) in pig iron, carbon steel, alloy steel.

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.

This Part of GB/T 223 specifies the determination of nickel content with dimethylglyoxime direct photometric method and extraction separation - dimethylglyoxime spectrophotometric method.

This part of GB/T 223 specifies the determination of acid-soluble silicon and total silicon content in steel and iron by the reduced molybdosilicate spectrophotometric method. This part applies to the determination of silicon content in steel and iron which have a mass fraction of 0.010% ~ 1.00%.

This Part of GB/T 223 specifies the determination of chromium content with visual titration or potentiometric titration method.

This Part of GB/T 223 specifies the determination of phosphorus content with bismuth phosphomolybdate blue spectrophotometric method and antimony phosphomolybdate blue spectrophotometric method.

This part of GB/T 223 specifies a gravimetric method for the determination of the sulfur content in steels and iron, excluding steels containing selenium. The method is particularly suitable as a reference method for the standardization of samples on which certified standard values are to be established.
