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 % and 2,0 %. The method can be adapted to lower or higher nickel contents by changing the test portion or the dilution process, provided the criteria in 5.2.2 and 5.2.3 are still met.

This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of lead content in non-alloy and low alloy steels. The method is applicable to lead contents between 0,005 % and 0,5 %. The method can be adapted to lower or higher lead contents by changing the test portion or the dilution process, provided the criteria in 5.2.2 and 5.2.3 are still met.

This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of calcium content in non-alloy and low alloy steels. The method is applicable to calcium contents between 0,000 4 % and 0,012 %. The method can be adapted to higher calcium contents by changing the test portion or the dilution process, provided the criteria in 5.2.2 and 5.2.3 are still met.
