| Published By | Publication Date | Number of Pages |
| ISO | 2018-10 | 22 |
Le présent document spécifie une méthode spectrophotométrique de détermination de l'azote dans l'acier.
La méthode s'applique à la détermination des teneurs en azote comprises entre 0,000 6 % et 0,050 % dans les aciers faiblement alliés et entre 0,010 % et 0,050 % dans les aciers fortement alliés.
La méthode ne s'applique pas aux échantillons contenant des nitrures de silicium ou ayant une teneur en silicium supérieure à 0,6 %.
