Particle size distribution in sieve analysis. The data is represented according to the mass-based distribution of particles. Summing up the quantities in the various particle size fractions (starting with the smallest fraction) yields the so-called "cumulative curve". Sieve analysis is suitable for particle sizes from approximately 5 µm to 125 mm.
