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.
