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.
