硬质合金．火焰原子吸收光谱法化学分析．第2部分：含量为0.001至0.02％（m/m）钙；钾；镁和钠的测定

Hardmetals. Chemical analysis by flame atomic absorption spectrometry. Part 2: Determination of calcium, potassium, magnesium and sodium in contents from 0,001 to 0,02 % (m/m)

DS/EN 27627-2-1993 发布历史

This part of ISO 7627 specifies the method to be used for the determination of calcium, potassium, magnesium and sodium contents of hardmetals within the range 0.001 to 0.02 % (mlm) by flame atomic absorption spectrometry. General requirements concerning the field of application, prin-ciple, interfering elements, apparatus, sampling and test report are given in ISO 7627/1. NOTE — In low concentrations, the determination of these elements is very critical. Every care should be taken to avoid contamination from atmosphere and reagents.
