本文件规定了铸造合金镁材料的等级和相应要求。本文件根据化学成分分类规定了两组镁合金等级。第一组涉及镁合金锭的牌号。第二组研究镁合金铸件的牌号。本文件还规定了从铸造样品加工的试件上测量的机械性能。本文件不包括镁合金铸件的交货技术条件（见EN 1559-1[7]和EN 1559-5[8]）。

This document defines the grades and the corresponding requirements for cast alloyed magnesium materials. This document specifies 2 groups of magnesium alloy grades by a classification based on the chemical composition. The first group deals with grades for magnesium alloy ingots. The second group deals with grades for magnesium alloy castings. This document also specifies mechanical properties measured on test pieces machined from cast samples. This document does not cover technical delivery conditions for magnesium alloy castings (see EN 1559-1 [7] and EN 1559-5 [8]).
