This standard specifies the determination methods of the total amount of rare earths in rare earth ferroalloys, including oxalate weighting method, EDTA Titrimetric method and Inductance coupled plasma emission Light spectrum method. It is suitable for the accurate determination of the total amount of rare earths in rare earth ferroalloys. The oxalate weighting method and EDTA Titrimetric method are suitable for the determination of the total amount of rare earths in the range of 10.00% to 90.00%, and the Inductance coupled plasma emission Light spectrum method is suitable for the determination of the main rare earth elements in the range of 1.00% to 20.00%. The standard provides the scope of application of different methods and arbitration methods to ensure the accuracy and Reliability of the determination results.
