1.1 Scope: This standard defines magnetic, thermal,physical and mechanical characteristics and properties of commercially available permanent magnet materials as
listed in Table 1.
There are a large number of permanent magnet materials in use which are not described in this document. These materials generally fall into one of the following categories:
(a) Older materials that have been largely replaced by new materials.
(b) Materials made by only one company with a specialized and limited use.
(c) Materials evolving. from development status to production which at this time are not mature from a commercial viewpoint.
For reference purposes, the principal magnetic properties of the materials in the above categories are listed in Appendix A.
1.2 Objective: The objective of this standard is to establish criteria by which users of permanent magnet materials may be assured of magnets manufactured to present commercial standards.

2.1 Definitions: The following definitions characterize materials covered in this standard:
2.1.1 Permanent Magnet (Magnetically Hard)
Material: A permanent magnet material, also designated as a magnetically hard material, has a coercive force gener-ally greater than 120 Oe.
2.1.2 Individual Magnet: The term individual magnet denotes a magnet purchased in a size and shape to be ready for direct incorporation into a magnetic circuit.
2.1.3 Bulk Magnet Material: The term bulk magnet material designates bar, rod, slab, strip, sheet, etc., from which the purchaser cuts, stamps or forms individual magnets.
2.1.4 Polarity of a Magnetized Magnet: The North Pole of a magnet is that pole which is attracted to the geographic North Pole. Therefore, the North Pole of a magnet will repel the north seeking pole of a magnetic compass.
2.1.5 Demagnetized Magnet: For the purposes of this standard, a magnet shall be considered demagnetized if, when any of its poles is dipped in soft iron powder (of -5, + 10 mesh), not more than 3 particles of powder adhere to it anywhere upon withdrawal.
2.2 Terms: A glossary of terms commonly used with permanent magnetic materials is given in Appendix B.
