Ferronickel -- Determination of trace-element content by electrothermal atomic absorption spectrometric method -- Part 3: Determination of antimony content
This part of ISO 11438 specifies an electrothermal atomic absorption spectrometric method for the determination of antimony in the range of 1,0 g/t to 5,0 g/t in ferronickel, according to the principle of standard additions. The general requirements concerning the apparatus, sampling, dissolution of the test sample, procedure, calculation and test report are given in ISO 11438-1.
