Scope
This part of GB/T 7731 specifies the determination of antimony content in tungsten iron by the rhodamine B photometry method and inductively coupled plasma atomic emission spectrometry method. This part is applicable to the determination of antimony content in tungsten iron. The determination range (mass fraction) of the rhodamine B photometry method is 0.010% to 0.060%; the determination range (mass fraction) of the inductively coupled plasma atomic emission spectrometry method is 0.010% to 0.15%.
