This specification covers technically important, commercially available, magnetically hard sintered ceramic ferrite permanent magnets. Both barium and strontium ferrite materials are covered by this specification. Both isotropic (1 type) and anisotropic (12 types) are covered. A cross reference to both IEC and MMPA designations is provided. The magnetic property requirements for each type are defined as is the method of test. Other defined requirements include the workmanship. Typical physical properties are listed in the appendices.
