Sieve mesh sizes are based on dimensions of the mesh size opening, or on the number of openings per linear inch.The two major standards governing test sieves and appropriate sizes are astm e11 and iso 5653310-1, both of which specify parameters for aperture dimensions, mesh size, and statistical variations.Opening sizes and mesh diameters for test sieves are often duplicated between these.
