Percent Passing Vs. Percent Retained - Quality in California

2011-5-6 · Percent passing is the amount of the sample that PASSES the sieve in question. So if you see the following gradation: #4 100%. #8 55%. #16 23%. You can determine that 55% of the sample is smaller than the #8 sieve because 55% of the sample passed through the #8 sieve. Another way that a gradation result can be shown is percent retained.
