Scope

This Standard specifies the requirements, test methods, inspection rules, marking, packaging,
transportation, storage and quality certificate of rapidly-quenched neodymium iron boron
permanent magnetic powder.
This Standard is applicable to isotropic neodymium iron boron permanent magnetic powder
produced by single-rolling or atomized rapid quenching process. Specifically speaking, single-
rolled rapidly-quenched neodymium iron boron permanent magnetic powder is used to
manufacture bonded magnets through processes, such as: molding, injection molding, extrusion
molding and calendaring molding, etc.; atomized rapidly-quenched neodymium iron boron
permanent magnetic powder is used to manufacture bonded magnets through processes, such
as: injection molding and extrusion molding, etc.
