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]).
