This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of calcium content in non-alloy and low alloy steels.<\/p>\n

The method is applicable to calcium contents between 4\u00c2 \u00c2\u00b5g\/g and 120\u00c2 \u00c2\u00b5g\/g.<\/p>\n

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<\/span> and 6.2.3<\/span> are still met.<\/p>\n
