About Sieve Standards

Different sieve standards are used worldwide for particle size analysis. Here's a brief overview:

  • Tyler: Based on the number of meshes per inch, with each size being √2 times the previous one.
  • US Standard: Similar to Tyler series but with some variations in specific sizes.
  • ASTM: American Society for Testing and Materials standard, widely used internationally.
