This standard specifies methods for the determination of nickel content in sintered nickel and nickel oxidation by electrolysis weighting, as well as methods for the determination of cobalt, copper, iron, zinc, and manganese content by Inductance Coupled Plasma Atomic Emission Spectroscopy (AES). It is suitable for the analysis of the content of these elements in sintered nickel, nickel oxidation, and partially reduced nickel oxidation. The standard describes the experimental procedures and reagent requirements in detail, providing a scientific basis for the chemical composition analysis of related products.
