Applicability and limitations
Mass fraction wt%; GB/T5231—2012, Table 3, row 28, designation T37900. Zn is the balance; Tabulated total impurities ≤0.8%; The calculation scope must be confirmed under Clause 2.3 and the footnotes for this row; a partial sum of listed elements cannot replace complete analysis. Table 3, note a: nonmagnetic-brass condition Fe≤0.030% applies only to nonmagnetic brass and is not applied to this leaded-brass row. Clause 2.2: unlisted elements are not entered as zero; Clause 2.4: the Zn balance must not be mechanically converted into a guaranteed range. Table 3, note c: total impurities for this row are the sum of measured contents of the impurity elements listed in the table.
