DESCRIPTION
BS 6200-3.33.3:1985
This standard BS 6200-3.33.3:1985 Sampling and analysis of iron, steel and other ferrous metals. Methods of analysis. Determination of tungsten is classified in these ICS categories:
- 77.100 Ferroalloys
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).
