WebbRemove the sand fraction from the oven, cool and sieve through a sieve set -2mm; 1mm; 0.5mm; 0.25mm; 0.125mm; 0.05mm + base. Transfer the contents of each sieve to a weighed 50 ml beaker, weigh and calculate the weight of each fraction. Express as a percentage of the original weight of peroxidised soil, using the size classes given above. Size ranges define limits of classes that are given names in the Wentworth scale (or Udden–Wentworth scale) used in the United States.

"WebbFoundry sands usually have a size distribution from 0,1 mm – 0,8 mm with a mean size between 0,2 mm and 0,45 mm. A standard parameter to express the size of molding sands is the AFS fineness number (AFS = American Foundry Society). This number is calculated from the size distribution, which is determined by standard ASTM sieves. " - Size fraction for sand
