19、ommercially available magnesium alloys into a number of grades suitable for the applications to which they might be put. Some of the alloys referenced in this standard can be the subject of a patent or of patent applications and their listing herein is not to be construed in any way as the granting
20、of a licence under such patent rights. 1 Scope This European Standard specifies the chemical composition of magnesium alloy ingots. It also specifies the chemical composition of magnesium alloy castings. It also specifies the mechanical properties of separately cast samples of these alloys (see clau
21、se 6). By agreement, it also specifies the mechanical properties of magnesium alloy castings determined from samples cut from a casting. 2 Normative references This standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the ap
22、propriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication
