European Norm
77.040.30 Chemical analysis of metals
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 4 µg/g and 120 µg/g.
The method can be adapted to higher calcium contents by changing the test portion or the dilution process, provided the criteria in 6.2.2 and 6.2.3 are still met.
