The symbols used in the formula are as follows:
T = tolerance being calculated.
A = percent which the weight of the component with the heavier average particle-weight is of the weight of both components.
B = percent which the weight of the component with the lighter average particle-weight is of the weight of both components.
H = average particle-weight for the component with the heavier average particle-weight.
L = average particle-weight for the component with the lighter average particle-weight.
R = ratio of the average particle-weight for the component with the heavier average particle-weight to the average particle-weight for the component with the lighter average particle-weight. R = H / L.
T1 = regular tolerance for the kind of seed (chaffy or nonchaffy) and for (100B)/(B + A/R).
In determining the values for A and B in the formula, the sample shall be regarded as composed of two parts:
