This part specifies the method for the determination of copper content in magnesium and magnesium alloys. This section applies to the determination of copper content in magnesium and magnesium alloys. The measurement range of method one: 0.00030%~0.200%; the measurement range of method two: 2.00%~4.00%; the measurement range of method three: 0.0020%~0.40%. Method 3 of this part is not applicable to magnesium alloys containing zirconium.
