标准摘要
[中文适用范围]： 该方法适用于镁及镁合金中0.002%至0.8%（m/m）之间铜含量的测定。 该方法并不完全适用于硅含量超过1%（m/m）的合金的特殊情况，对此应按附录所述进行修改。 [外文原描述]： The method is applicable to the determination of copper content between 0,002 and 0,8 % (m/m) in magnesium and magnesium alloys. The method is not completely applicable in the special case of alloys with silicon contents exceeding 1 % (m/m), for which it should be modified as desribed in the annex.
英文名称Aluminium and aluminium alloys — Determination of copper content — Oxalyldihydrazide photometric method
