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, this part of IEC 60404 provides values for the densities of the materials and the ranges of their chemical compositions.
NOTE
Some additional physical data and mechanical reference values concerning the magnetic materials are given in Table A.1 for information and comparison purposes.
