For example, a 36 mesh screen will have 36 openings while a 150 mesh screen will have 150 openings. Since the size of screen (one square inch) is constant, the higher the mesh number the smaller the screen opening and the smaller the particle that will pass through. Generally US Mesh is measured using screens down to a 325 mesh (325 openings in

Equivalent mesh sizes from 5 μm to 25.4 mm also exist. [1] [2] [3] Available sieve sizes are usually regulated by standards. Those in common use are ISO 565:1990 and ISO 3310-1:2000 (international), [4] EN 933-1 (European) [5] and ASTM E11:01 (US). EN standards are available with national 'badging' so appear as BS EN, FR EN, DE, etc.

Sep 20,  · The mesh only says Standard size which has 16x18 strands per in. Your math is missing that you have to subtract the area consumed by the wires before you divide by 18. So hole size would be (25.4- (18x.28))/18=1.13mm (assuming .011"=.28mm wire). Finer mesh screens are available, but may not be on the shelf at the hardware store down the street.

Thus a mesh size of unity (1 in.) would have an opening of 20.84 mm and a nominal wire diameter of 4.56 mm. The difference in screen opening between the values. calculated using the empirical equation and those re- ported in Table 1 are less than 10% with the exception of 12 mesh size where the difference approaches 15%.
