- Scope
- This document specifies a method for the determination of the Fisher particle size of powders of metals and their compounds. This document is applicable to the determination of the Fischer particle size of metals and their compounds (carbides, nitrides and oxides, etc.) with a powder particle size of 0.5 μm to 50 μm. This document does not apply to powder particles with poor axial symmetry and irregular shapes (such as flakes and fibers, etc.), nor does it apply to mixtures of different powders and powders containing binders or lubricants. If necessary, it shall be adopted after negotiation between relevant parties.
