GB/T 3249-2022 Test method for Fisher number of metal powders and related compounds
Abstract
This document specifies the method for determining the Fe size of powders of metals and their compounds.
This document is applicable to the determination of the Fe size of powders of metals and their compounds (carbides, nitrides, and oxides, etc.) with a particle size of 0.5μm to 50μm.
This document is not applicable to powders with poor axial symmetry and irregular shapes (such as flaky and fibrous shapes, etc.), nor to mixtures of different powders and powders containing binders or lubricants. If it is necessary to use them, the parties concerned should consult and use them after reaching an agreement.
