Magnesium and magnesium alloys - Magnesium alloys for cast anodes
This European Standard specifies the grades and the corresponding requirements for magnesium alloys for cast anodes.
This European Standard specifies 2 groups of cast magnesium alloy grades by a classification based on chemical composition. The first group deals with magnesium alloy ingots for anodes. The second group deals with magnesium alloy anode castings.
This European Standard specifies chemical composition, designation, testing and inspection documentation.
This European Standard does not cover technical delivery conditions for magnesium alloy anode castings (see EN 1559-1 [3] and EN 1559-5 [4]).
Magnesium und Magnesiumlegierungen - Magnesiumlegierungen für Gussanoden
Diese Europäische Norm legt die Sorten und die zugehörigen Anforderungen der Magnesium-legierungen für Gussanoden fest.
Diese Europäische Norm legt 2 Gruppen von Magnesiumguss-Legierungssorten, nach der Einordnung anhand der chemischen Zusammensetzung, fest. Die erste Gruppe behandelt Blockmetalle aus Magnesium¬legierungen für Anoden. Die zweite Gruppe behandelt Gussanoden aus Magnesiumlegierungen.
Diese Europäische Norm legt die chemische Zusammensetzung, Bezeichnung, Prüfung und Prüfbe-scheinigung fest.
Diese Europäische Norm legt nicht die Technischen Lieferbedingungen für Gussanoden aus Magnesium¬legierungen fest (siehe EN 1559 1 [3] und EN 1559 5 [4]).
Magnésium et alliages de magnésium - Alliages de magnésium pour anodes coulées
La présente Norme européenne spécifie les nuances et les exigences correspondantes des alliages de magnésium pour anodes coulées.
La présente Norme européenne spécifie 2 groupes de nuances d’alliages de magnésium moulé en utilisant une classification basée sur la composition chimique. Le premier groupe concerne les lingots en alliage de magnésium pour anodes. Le second groupe concerne les anodes coulées en alliage de magnésium.
La présente Norme européenne spécifie la composition chimique, la désignation, les essais et la documentation de contrôle.
La présente Norme européenne ne couvre pas les conditions techniques de fourniture des anodes coulées en alliage de magnésium (voir l'EN 1559-1 [3] et l'EN 1559-5 [4]).
Magnezij in magnezijeve zlitine - Magnezijeve zlitine za lite anode
Ta evropski standard določa razrede in ustrezne zahteve za magnezijeve zlitine za lite anode.
Ta evropski standard določa 2 skupini razredov litih magnezijevih zlitin z razvrstitvijo, ki temelji na kemijski sestavi. Prva skupina opisuje ingote magnezijevih zlitin za anode. Druga skupina opisuje ulitke anod iz magnezijevih zlitin.
Ta evropski standard določa kemijsko sestavo, poimenovanje, preskušanje in pregled dokumentacije.
Ta evropski standard ne zajema tehničnih dobavnih pogojev za ulitke anod iz magnezijevih zlitin (glej standarda EN 1559-1 [3] in EN 1559-5 [4]).
