Scope

This standard specifies the method for the determination of total rare earth content in mixed rare earth oxides of ionic rare earth ores. This standard is applicable to the determination of total rare earth content in mixed rare earth oxides of ionic rare earth ores. Measuring range: >80.00% to 99.00%. This standard does not apply to the determination of the total amount of rare earths with thorium and lead content > 0.1% in mixed rare earth oxides.
