Applicability and limitations
Mass fraction wt%; GB/T5231—2012, Table 3, row 12, designation T22130. 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. Table 3 Note e: The listed 0.5% is the upper limit of the sum of measured values of Sb+B+Ni+Sn, not the general impurity sum of Table 3; Unlisted elements shall be measured or confirmed by agreement.
