Applicability and limitations
Mass fraction wt%; GB/T5231—2012, Table 3, row 24, designation T36220. Zn is balance. Total table-listed impurities ≤0.4%; confirm the calculation scope under clause 2.3 and the row footnotes. A partial sum of listed elements does not replace complete analysis. Note a to Table 3: Fe≤0.030% for nonmagnetic brass applies only to that condition, not to this leaded-brass row. Clause 2.2: unlisted elements are not assigned zero. Clause 2.4: balance Zn must not be mechanically converted into a guaranteed range.
