Steel. Determination of Mo, Nb and W contents in alloyed steel. Inductively coupled plasma atomic emission spectrometric method - Determination of Nb Content Ingestion-build-61878 The standard test formula is1 Scope 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).
