Description / Abstract: Applies to refined, wrought and cast nickel within the ranges specified in table 1. The method is applicable to the independent determination of any one or more of the elements listed. The lower level for iron can be extended to less than 0,0025 % (m/m) provided a special standard solution is prepared. The upper limit for the determination of cobalt and copper can be raised to 2 % (m/m) by a minor modification to the method. For potential interferences, see clause 10.
