This International Standard specifies a photometric method for the determination of manganese in magnesium alloys containing zirconium, and/or rare earths, and/or thorium, and/or siIver.The method is applicable to the determination of manganese contents between 0.002 and 0.2 %.

This International Standard specifies a spectrophotometric method using the reduced silicomolybdic complex for the determination of silicon in magnesium and magnesium alloys.This method is applicable to the determination of silicon content between 0,01 and 0,6 %.The method does not apply to the special case of magnesium alloys containing rare earths or thori...

This International Standard specifies a volumetric method for the determination of zinc in magnesium alloys not containing cadmium.This method is applicable to the determination of zinc content between 0,10 and 8,0 %.

This International Standard specifies an alizarin sulphonate photometric method for the determination of soluble 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 zirconium contents between 0,1 and 1,0 % (m/m).The method does not apply completel...

This International Standard specifies a photometric method for the determination of manganese in magnesium and magnesium alloys which do not contain zirconium, rare earths, or thorium1).The method is applicable to the determination of manganese content less than 0,01 %.2)
