This International Standard specifies a spectrophotometric method for the determination of nickel in steel using dimethylglyoxime. The method is applicable to the determination of nickel mass fractions in the range of 0,10% and 2,0%. Cobalt, copper and manganese can cause interferences (see 7.3.2).
