This International Standard specifies a cinchonine gravimetric method for the determination of the tungsten content of ferrotungsten. It also specifies, in the annex, a spectrometric method for the determination of molybdenum which interferes with the determination.
The method is applicable to ferrotungsten having tungsten contents between 70 and 90 % (m/m).
