Metallic powders — Determination of particle size distribution by gravitational sedimentation in a liquid and attenuation measurement

Specifies methods which are suitable only where Stokes’ equation is applicable. They are suitable for all metallic powders containing particles in the size range 1 μm to 100 μm. Does not apply to powders: containing particles whose shape is far from equiaxial; which are mixtures; containing lubricant or binder; which cannot be dispersed in a liquid.
