Steel and iron — Determination of nitrogen content — Thermal conductimetric method after fusion in a current of inert gas (Routine method)

Aciers et fontes — Dosage de l'azote — Méthode par conductibilité thermique après fusion sous gaz inerte (Méthode pratique)

Abstract / scope

This International Standard specifies a thermal conductimetric method after fusion under inert gas for the

determination of nitrogen in steel and iron.

The method is applicable to nitrogen contents between 0,002 % (m/m) and 0,6 % (m/m).
