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.

This International Standard specifies the dimensions and method of production of reference test bars for magnesium alloy sand castings.

This International Standard specifies a gravimetric method for the determination of rare earths in magnesium alloys.The method is applicable to the determination of contents of rare earths between 0.2 and 10 %, in the absence of thorium.

This International Standard specifies an alizarin sulphonate photometric method for the determination of insoluble zirconium in magnesium alloys containing zirconium as an alloying element.Rare earths, thorium and silver do not interfere.The method is applicable to alloys having insoluble zirconium contents between 0,02 and 0,3 % (m/m).NOTE - Hafnium which i...
