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

General information

Current stage: 10.99 Effective date: Jan 15, 2023

Originator: ISO

Owner: ISO/TC 17/SC 1

Type: International Standard

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.
