ISO 1975-1973 Magnesium and magnesium alloys - Determination of silicon - Spectrophotometric method with the reduced silicomolybdic complex

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 thorium (this case is being studied).
