Sieve Sizes: A Guide to U.S. and Metric Sizes

May 03, 2022

<div><a href="/blog/sieve-sizes"><img loading="lazy" src="/Content/Images/uploaded/blog/sieving/sieve-sizes/sieve-sizes-hero.jpg" alt="ISO and ASTM Sieve Sizes Guide" style="display: block; margin-left: auto; margin-right: auto; width: 100%; max-width: 715px;" /> </a></div><p>The two major standards governing test sieves and appropriate opening sizes are ASTM E11 and ISO 565/3310-1, both of which specify parameters for aperture dimensions, mesh size and statistical variations. We take a dive into sieve sizes and give guidance on the basics, popular test application opening sizes, maintenance, and an opening size conversion table.</p>
