This graticule features progressively doubling circle areas, altering diameters by the square root of 2, to align with standard sieve series for particle sizing. Each particle is categorized into a size class defined by two adjacent circles, representing size limits. Size distribution is determined based on the diameter of circles with equal projected areas, covering particles from 150 microns to 0.38 microns. Number and weight-based size distributions are calculated separately, with final results presented as cumulative percentages.
