This document presents a protocol for the application of semi-quantitative Wavelength Dispersive X-Ray Fluorescence Spectrometry (WD-XRFS) commercial packages for assessment of the concentration of
rare earth elements (REEs) contained in magnet scrap from End of Life (EOL) products intended for recycling.
The standard can be subdivided into two parts:
1. The first part outlines a procedure for safe handling of the magnet scrap
2. The second part specifies measurement of the REE content in the magnet scrap
WARNING — The use of this document may involve hazardous materials, operations, and equipment. This document does not purport to address any safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The concentration ranges of samples that may be appropriately analyzed by this method are given in
Tables 1, for each type of magnet scrap included in the standard.

NOTE Standardless XRF analysis will be carried out on all the elements between Na and U. The final report will contain the elements in scope that are over 1 mass %.
