Particle Size Distribution Functions

Since it is often not possible to obtain particle size data from d p = 0 to d p = ∞, it is desirable to use a function with a minimum number of free parameters to describe the particle size distribution. From such a function all moments can be calculated. If the function has 3 free parameters, for example, such as the mean, standard

Standard Test Method for Particle-Size Analysis of Soils

Withdrawn Rationale This test method covers the quantitative determination of the distribution of particle sizes in soils. The distribution of particle sizes larger than 75 μm (retained on the No. 200 sieve) is determined by sieving, while the distribution of particle sizes smaller than 75 μm is determined by a sedimentation process, using a hydrometer to secure the necessary data.
