Specifies a method for the determination of the niobium content in steel by means of inductively coupled plasma emission spectrometry.

This International Standard specifies a method for the determination of the niobium content in steel by means of inductively coupled plasma emission spectrometry.

This method is applicable to niobium contents between 0,005 and 5%(mass fraction).
