Steel and iron — Determination of molybdenum content — Thiocyanate spectrophotometric method

Aciers et fontes — Dosage du molybdène — Méthode spectrophotométrique au thiocyanate

This edition has been replaced by ISO 4941:2024.

Abstract / scope

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.
