Particle size distribution influences the physical and chemical properties of solids. Therefore this criterion is of highest importance in the context of science and quality control. Only if the size distribution remains constant, a steady product quality can be guaranteed, as the following examples show:

US standard test sieve series. A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering or sedimentology) to assess the particle size distribution (also called gradation) of a granular material. Sieve sizes used in combinations of four to eight sieves. Designations and Nominal Sieve Openings
Opening sizes and mesh diameters for test sieves are often duplicated between these two standards, making it easier to select the proper sieve size for your material. The above table is a list of all available sieves in U.S. and metric sizes for both ASTM E11 and ISO 565/3310-1. Sieve mesh opening sizes range from 5in (125mm) down to #635 (20µm).
Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.

In such situations it is more accurate to describe the sizes of the particles in sieve numbers, rather than as particle diameters. For an example of how sieve numbers are used to grade a commercial product, see abrasives. The sieves used in industry and the laboratory are precision products.
The well-proven RETSCH test sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the fabric of each test sieve is precisely joined into the frame and tautened.
Test Sieves At Endecotts every single test sieve is individually manufactured under the most stringent quality control procedures using only the finest materials. We use the most advanced computer scanning techniques to ensure precise test sieve apertures.
Sieve analysis has, in general, been used for decades to monitor material quality based on particle size. For coarse material, sizes that range down to #100 mesh (150μm), a sieve analysis and particle size distribution is accurate and consistent. However, for material that is finer than 100 mesh, dry sieving can be significantly less accurate.
Larger sieve openings (1 in. to 1/4 in.) have been designated by a sieve "mesh" size that corresponds to the size of the opening in inches. Smaller sieve "mesh" sizes of 3 1/2 to 400 are designated by the number of openings per linear inch in the sieve. The following convention is used to characterize particle size by mesh designation:
