Steel and iron -- Determination of molybdenum content -- Thiocyanate spectrophotometric method
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
Cancels and replaces the first edition (1978). Specifies a thiocyanate spectrophotometric method for the determination of the molybdenum content in steel and iron. Applicable to molybdenum contents between 0,005 % (m/m) and 0,125 % (m/m). Vanadium and tungsten interfere with the measurement if, because of their contents, the V/Mo ratio is greater than 16 or the W/Mo ratio is greater than 8.
