PERCENT PASSING CALCULATION (ARIZ 201)
To calculate percent passing you will need a scientific calculator with at least one memory.
Always add up all the weights, never change the amount in the total box. If the calculated total is 1.0% or less from the total in the total box, adjust the number of the sieve weight with the largest amount retained, except for the passing #4.
COARSE SIEVE a. To get the Coarse sieve factor, divide 100 by the total weight of sample (the number in the
total box).b. Place the factor in the memory of the calculator (MR+).c. Enter 100 in the calculator, subtract the first weight retained, times (x) the factor (memory
recall) (MR),then the = key this will give you the % passing that sieve.d: Keeping that number in the calculator subtract the next weight retained, multiply it by the
factor (MR) until all % passing is calculated and recorded. e. Continue this down to the #4 weight retained.f. Then do a check on the pass #4 by, multiplying the weight passing the #4 times the factor
(MR).
FINE SIEVE Always add up all the weights, never change the amount in the total box. If the calculated total is 1.0% or less from the total in the total box, adjust the number of the sieve weight with the largest amount retained except, for the passing #200.
a. Subtract the “Total Dry Weight” from the “Dry Wt. of -#4 Split” weight to get the elutriationweight and record it in the box provided.
b. To get the fine sieve factor, take the % passing the #4 (whole number) and divide it by theadjusted split weight.
c. Place the factor in the memory of the calculator.d. Enter the % pass the #4 (whole number) in the calculator, subtract the weight retained on
the #8 sieve, multiply, (x) it by the factor (MR) = to get the % passing the #8.e. Keeping that number in the calculator subtract the next weight retained (#10), multiply (x) it
by the factor (MR) until all % passing is calculated and recorded.f. Continue this procedure down to the #200.g. Do a check on the pass #200 by multiplying the (weight passing the 200 sieve plus + the
elutriation weight) by the factor (MR).
When all the percent pass results are recorded, you may now record the percent retained for each sieve. Start with the largest % pass and subtract the next smaller % pass from it. Continue this down to the #200 sieve(Rounded).
