This part of IEC 60404 specifies minimum values for the principal magnetic properties of, and dimensional tolerances for, technically important magnetically hard materials (permanent magnets).
For information purposes only, the standard provides values for the densities of the materials and the ranges of their chemical compositions.
NOTE Some additional physical and mechanical reference data concerning the magnetic materials is given in table A.1 for information and comparison purposes.
