Interactive FAQ

What is the difference between cumulative percent passing and percent passing?

Cumulative percent passing considers the material retained on all sieves, while percent passing only considers the material passing through a specific sieve.

How do I interpret the results?

The results indicate the proportion of material that passes through each sieve size.
