a Refer to Section 14 for the application of tolerances for chaffy , super chaffy, and non-chaffy seeds.
b If it is necessary to conduct a noxious-weed seed examination, see section 2.3 to determine size of the working sample. For those kinds listed
that show over 500 grams as the minimum weight for purity analysis, the actual amount given shall also be considered the minimum quantity to be examined for noxious-weed seeds. In no other cases does the amount examined for noxious-weed seeds need to exceed 500 grams for
raw seed or 1,000 grams for coated, encrusted or pelleted seeds. c Figures in parentheses are the average number of seeds per gram to be used in computations of special tolerances. See section 13.2 d The number of seeds per pound or the weight of 1,000 seeds can be calculated in the laboratory for individual lots from the sample submitted. e
