(Main)Steels - Determination of niobium - Spectrophotometric method
Steels - Determination of niobium - Spectrophotometric method
This document specifies a spectrophotometric method for the determination of niobium in steels.
The method is applicable to all grades of steels with niobium contents up to 1,3 % (by mass), with a lower limit of detection of 0,002 % (by mass).
The precision data of the present method are given in Annex A.
Stähle - Bestimmung von Niob - Photometrisches Verfahren
