Scope

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 is applicable to the determination of phosphorus content in pig iron,
cast iron, iron powder, carbon steel, low alloy steel and alloy steel and is not
applicable to niobium and wolfram steel. The determination scope of Method I
is 0.005% ~0.300% mass fraction while the determination scope of Method II
is 0.01% ~0.06% mass fraction.
