This European Standard specifies a material designation system for magnesium and magnesium alloys either by numbers or by symbols for castings including anodes and ingots intended for remelting.
The designation system by numbers is only applicable to standardized magnesium and magnesium alloys (see 2.1).
The designation system by symbols is applicable to
a) standardized magnesium and magnesium alloys (see 2.1);
b) non-standardized magnesium and magnesium alloys (see 2.2).
NOTE 1 – The standardized designation by symbols does not necessarily imply that the material is standardized.
NOTE 2 – Magnesium and magnesium alloys for aerospace applications referred to in European standards prepared by AECMA (fr: Association Européenne des Constructeurs de Matériel Aérospatial) have different designations.
