This International Standard specifies a gravimetric method for the determination of thorium in magnesium alloys.The method is applicable to products having thorium contents between 0,2 and 5,0 % (m/m).

This International Standard specifies a flame atomic absorption spectrometric method for the determination of the zinc content of magnesium alloys.The method is applicable to products having zinc (Zn) contents between 0,1 and 6 % (m/m).

This International Standard specifies a photometric method using dimethylglyoxime (oxidized complex) for the determination of nickel in magnesium and its alloys.The method applies to the determination of nickel contents between 0,0005 and 0,05 %.

This International Standard specifies a photometric method using chromazurol S for the determination of aluminium in magnesium and certain magnesium alloys.The method is applicable to the determination of aluminium content between 0,01 and 0,20 %.This method does not apply to alloys containing zirconium and/or rare earths and/or thorium.

This International Standard specifies the chemical composition and mechanical properties of magnesium alloys for wrought products in the form of bars and solid sections, tubes and hollow sections, forgings, and plate and sheet.
