本文件规定了火焰原子吸收光谱法（FAAS）的测定方法 钢和铸铁中镍含量的测定。 该方法适用于镍含量在0004%（重量百分比）和2.0%（重量百分比）之间的情况。 该方法可通过改变试验部分或试验条件来适应较低或较高的镍含量 稀释过程，前提是仍满足6.2.2和6.2.3中的标准。交叉引用:EN ISO 648EN ISO 1042EN ISO 14284ISO 5725:1986EN ISO 3696购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of nickel content in steels and cast irons. The method is applicable to nickel contents between 0,004 % (weight percent) and 2,0 % (weight percent). The method can be adapted to lower or higher nickel contents by changing the test portion or the dilution process, provided the criteria in 6.2.2 and 6.2.3 are still met.Cross References:EN ISO 648EN ISO 1042EN ISO 14284ISO 5725:1986EN ISO 3696All current amendments available at time of purchase are included with the purchase of this document.
