铜合金 铅含量的测定 火焰原子吸收光谱法

[中文适用范围]： 该方法适用于作为合金元素或杂质的铅含量在0.01%至5.0%（m/m）之间。 通过适当修改样品质量，下限可扩展至 0.002% (m/m)。 ISO 4749规定了原理、试剂、仪器、取样、程序、结果表达和测试报告。 [外文原描述]： The method is applicable to contents of lead as an alloying element or an impurity between 0.01 and 5.0 % (m/m). By appropriate modification of sample mass, the lower limit may be extended to 0.002 % (m/m). ISO 4749 specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
