NF EN ISO 3581

Le présent document spécifie les caractéristiques de classification des électrodes enrobées, en fonction du métal fondu hors dilution, à l'état brut de soudage ou après traitement thermique, pour le soudage manuel à l'arc des aciers inoxydables et résistant aux températures élevées. Il permet une classification utilisant un système basé sur la composition nominale ou sur le type d'alliage. Il existe d'autres normes relatives à la classification des électrodes enrobées pour le soudage manuel à l'arc des aciers. Ce sont les normes NF EN ISO 18275, NF EN ISO 2560, NF EN ISO 14172 et NF EN ISO 3580.
