Standard Test Methods for Determining Average Grain Size

4.1.2 Planimetric Procedure—The planimetric method involves an actual count of the number of grains within a known area.The number of grains per unit area, N A, is used to determine the ASTM grain size number, G.The precision of the method is a function of the number of grains counted. A precision of ±0.25 grain size units can be attained with a reasonable amount of effort.

Particle-size distribution - Wikipedia

Particle-size distribution - Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
