### Particle Size Distribution - D10, D50 & D90 - Sieve Analysis

The most commonly used metrics when describing particle size distributions are D-Values (D10, D50 & D90) which are the intercepts for 10%, 50% and 90% of the cumulative mass. D-values can be thought of as the diameter of the sphere which divides the sample's mass into a specified percentage when the particles are arranged on an ascending mass basis.
