Particle Size Distribution an overview ScienceDirect
Aug 08, 2011 · D.F. Heaney, in Handbook of Metal Injection Molding, 2012. 3.3.4 Particle size distribution (ASTM B 822 10, ISO 133201) Particle size distribution (PSD) is typically measured using laser stering or diffraction techniques for MIM powders. In this technique the ''halo'' of diffracted light is measured on particles suspended in a liquid.

Mesh (scale) Wikipedia
Mesh is a measurement of particle size often used in determining the particlesize distribution of a granular material.For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
