This document specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the vanadium content in steel. The method is applicable to vanadium contents between 0,01 % (mass fraction) and 0,80 % (mass fraction), provided that the tungsten content in a 1,0 g test portion is not higher than 1,0 % and\/or the titanium content is not higher than 0,5 %.<\/p>\n
