Scope

This Part of GB/T 223 specifies the determination of nickel content with
dimethylglyoxime direct photometric method and extraction separation -
dimethylglyoxime spectrophotometric method.
The method one of this Part is applicable to the determination of nickel
content with mass fraction 0.030% ~ 2.00% in pig iron, iron powder, carbon
steel and alloy steel; the method two of this Part is applicable to the
determination of nickel content with mass fraction 0.010% ~ 0.50% in pig iron,
carbon steel, alloy steel and precious alloy.
