For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. Metal surfaces mechanically polished are designated as having a mechanical finish related to the abrasive used. Equivalent mesh sizes from 5 μm to 25. Available sieve sizes are usually regulated by standards. EN standards are available with national ‘badging’ so appear as BS EN, FR EN, DE, etc.

2 smaller in cross-sectional area than the previous sieve. For example the series 80mm, 63, 40, 31. 5, 20, 16, 14, 10, 8, 6. 8, 2 mm is routinely available in many European countries or the series with the larger steps 63, 31. 5, 16, 8, 4, 2, 1 mm, 500 μm, 250, 125, 63 μm is commonly used to grade aggregates in the construction industry. Equivalent mesh sizes from 5microns to 25. Particle Size – US Sieve Series and Tyler Mesh Size Equivalents”.
