Zinc and zinc alloys - Secondary raw material
This document specifies the requirements for the properties and condition of a specific range of tradeable secondary raw materials with a predominant zinc content.
This document defines these materials uniformly at the European level so that they can be traded within the economic cycle as raw materials with product character and their recycling is carried out specific to the material.
Zink und Zinklegierungen - Sekundärrohstoffe
Diese Europäische Norm legt die Anforderungen an die Merkmale und Beschaffenheit eines bestimmten Bereiches marktgängiger zinkhaltiger Sekundärrohstoffe mit überwiegendem Zinkgehalt fest.
Die vorliegende Norm definiert diese Stoffe einheitlich auf europäischer Ebene, damit sie im Wirtschaftskreislauf als Sekundärrohstoffe mit Produktcharakter gehandelt werden können und ein Recycling stoffspezifisch durch-ge-führt wird.
Zinc et alliages de zinc - Matières premières secondaires
La présente Norme Européenne spécifie les exigences applicables aux propriétés et à l'état d'une gamme spécifique de matières premières secondaires à base de zinc commercialisables, à haute teneur en zinc.
La présente Norme définit ces produits de manière uniforme au niveau européen de manière à ce qu'ils puissent être commercialisés dans le cadre du processus économique sous forme de matières premières ayant les caractéristiques d'un produit et de façon à ce que leur recyclage soit réalisé en fonction de ce dernier.
