Scope

Scope: This document specifies the method for determining the bulk density of sintered neodymium-iron-boron permanent magnet alloy powder. This document is applicable to the determination of the bulk density of sintered neodymium-iron-boron permanent magnet alloy powder, with a particle size range of (1.5~50.0) μm. For sintered neodymium-iron-boron permanent magnet alloy powder outside this range, this document can be used as a reference for measurement. The measurement of the bulk density of samarium-cobalt permanent magnet alloy powder can also be referenced to this document; Main technical content: This document specifies the method for determining the bulk density of sintered neodymium-iron-boron permanent magnet alloy powder from aspects such as terminology, definitions, principles, instrumentation, analysis steps, precision, repeatability, and result reporting. The measurement range is (1.5~50.0) μm.
