Example—If the sample tested shows 4.40% of weed seeds, other crop seeds and inert matter, the tolerance is computed as 
follows: Find 4 in the “value” column, then .40 at top of table. These two intersect at 1.04; hence the tolerance is 1.04%. 




Table of Tolerance for Inert Matter, Weed Seed, and Crop Seed for the following: Poa spp., Argostis spp. Festuca spp., 
bromegrass, crested wheatgrass, orchard grass, velvet grass, tall oatgrass, meadow foxtail, sweet vernalgrass, Rhodes 
grass, Dallis grass, carpet grass and Bermuda grass, and mixtures containing these seeds singly or combined in 
excess of 50%
