Web(1) Use a 4/64” round hole sieve for samples containing a substantial amount of green seed (small kernels) Material passing through the 4/64” round hole sieve is considered as foreign material (2) Use a 1/20” round hole sieve for samples that do not contain green seeds (small kernels) This sieve permits reclaiming of a larger
A sieve analysis (or gradation test) ... To do so, add up the total amount of aggregate that is retained in each sieve and the amount in the previous sieves. The cumulative percent passing of the aggregate is found by subtracting the percent retained from 100%.
