Applicability and limitations
Mass fraction wt%; GB/T5231—2012, Table 3, row 14, designation C26130. Zn is the balance; A dash means unspecified; it is not entered as zero. Clause 2.2: single values for other impurity elements are maxima. Tabulated total impurities ≤0.4%, evaluated under Clause 2.3; a partial sum of listed values cannot replace complete analysis.
