该方法适用于国际标准中列出的所有类型的铜和铜合金中锑含量在0.001%至0.1%（m/m）之间的情况。可通过适当修改试验部分的质量、提取体积和细胞路径长度来扩展应用范围。覆盖低浓度和高浓度的具体建议正在准备中。ISO 5956规定了原理、试剂、仪器、程序、结果表达和试验报告。

The method is applicable to antimony contents between 0.001 and 0.1 % (m/m) in all types of copper and copper alloys listed in International Standards. The range of application may be extended by appropriate modification of the mass of the test portion, the extraction volume and the cell path length. Specific proposals to cover lower and higher concentrations are in preparation. ISO 5956 specifies principle, reagents, apparatus, procedure, expression of results and test report.
