Sampling and analysis of iron, steel and other ferrous metals - Methods of analysis - Determination of silicon - Steel and cast iron: spectrophotometric method for silicon contents from 0.05% (m/m) to 1.0% (m/m)
This International Standard specifies a spectrophotometric method using reduced molybdosilicate for the determination of total silicon in steel and cast iron.
The method is applicable to silicon contents between 0,05 and 1,0 % (m/m) in steel and cast iron soluble in one or the other of the alternative acid mixtures.
