1. PURPOSE

This directive establishes procedures for the factor analysis of millet seed under the 

Agricultural Marketing Act of 1946 (AMA), as amended

2. REPLACEMENT HIGHLIGHTS

This directive supersedes FGIS Directive 9180.72, dated 4/5/02. It is revised to remov

moisture content analysis as a factor that can be determined and to make other minor 

editorial changes

3. GENERAL INFORMATION

There are no classes, subclasses, or grades for millet seed. Inspection of millet seed

is on a factor only basis. Factors analyzed are foreign material and test weight per

Winchester bushel. In addition to the analysis described in this directive for foreign

material and test weight per Winchester bushel, an applicant may request an analysis 

for other factors such as purity, stones, insects, etc

4. DEFINITION OF MILLET SEED

Millet seed consist of 50.0 percent or more of whole millet seed before the removal of

foreign material

Whole kernels are kernels with more than three-fourths of the kernel present

Basis of Determination. A visual appraisal of the sample is sufficient to determine if 

it meets the definition of millet seed. However, if analysis is necessary, make it before 

removing foreign material on a representative portion of approximately 25 grams

5. FOREIGN MATERIAL

Foreign material is all matter ,other than millet seed, that can be removed from the 

original sample by use of an approved device according to procedures prescribed 

in the Federal Grain Inspection Service (FGIS) instructions. Foreign material is also

underdeveloped, shriveled, and small pieces of millet kernels removed in properly 

separating the material other than millet seed, and which cannot be recovered by 

properly rescreening or recleaning and includes detached millet hulls

Basis of Determination. Foreign material is determined on a representative portion

of the original sample of sufficient size to provide approximately 1 1/8 to 1 1/4 

quarts of mechanically cleaned millet seed and approximately 50 grams cut from the 

mechanically cleaned sample

Foreign material is determined in two steps: Mechanically separated foreign material 

and handpicked foreign material

STEP 1. Procedure for determining mechanically separated foreign material using the

 Carter Dockage Tester:

a. Set air control on 3

b. Set feed control to

c. Insert No. 000 riddle in the riddle carri

d. Insert No. 4 sieve in the top sieve carri

e. Insert No. 2 sieve in the middle sieve carri

f. Insert No. 7 sieve in the bottom sieve carri

g. Run sample portion through the Carter Dockage Test

h. Combine aspirated material in air collection pan and material ove

No. 000 riddle (excluding unthreshed millet seed). Total of this material i

the mechanically separated foreign material

Occasionally a small amount of unthreshed millet may pass over the 

riddle. Consider these unthreshed kernels as millet and return to the

sample

i. Combine all material passing over the top sieve, middle sieve, an

bottom sieve. Total of this material is the mechanically cleaned millet

seed

The material passing through the bottom sieve, although primarily 

foreign material, will usually contain small kernels of millet and cracked 

millet that you must reclaim by using the appropriate handsieve

(1) Use a 4/64” round hole sieve for samples containing a substantial 

amount of green seed (small kernels). Material passing through the

4/64” round hole sieve is considered as foreign material

(2) Use a 1/20” round hole sieve for samples that do not contain green 

seeds (small kernels). This sieve permits reclaiming of a larger

portion of cracked millet. Material passing through the 1/20” round

hole sieve is considered as foreign material

STEP 2. Procedure for determining handpicked foreign materia

a. Cut down the mechanically cleaned sample to approximately 50 gram

(combination of material that passed over the top, middle, and bottom 

sieve of the Carter Dockage Tester)

b. Handpick the 50-gram portion to remove all material other than mille

seed

Computing Foreign Material. Compute the percentage of foreign material by adding the

percentage of mechanically separated foreign material to the percentage of handpicked 

foreign material in hundredths (disregard thousandths) of a percent

STEP 1. (Weight of mechanically separated foreign material ÷ Original sample weight)

 x 100 = Percent of mechanically separated foreign material

STEP 2. (100 Percent - Percent of mechanically separated foreign material) ÷ 100 =

 Change of base factor

STEP 3. (Weight of handpicked foreign material ÷ Weight of handpicked portion) x 100

 = Percent of handpicked foreign material

STEP 4. Percent of handpicked foreign material x Change of base factor =

 Adjusted percentage of handpicked foreign material

STEP 5.  Percent of mechanically separated foreign material + Adjusted percentage o

 handpicked foreign material = Percent of foreign material

Certification. Show the percentage of foreign material on the work record and on the

certificate to the nearest tenth percent.

6. TEST WEIGHT

Test weight is the weight per Winchester bushel (2,150.42 cubic inches) as determined

using an approved device according to procedures prescribed in FGIS instructions

Basis of Determination. Determine test weight after removing mechanically separated

foreign material on a portion of sufficient quantity to overflow the kettle and before the 

removal of handpicked foreign material

The procedures for performing test weight determination are in Book II, Chapter 1,

Section 1.11 of the Grain Inspection Handboo

Certification. Record test weight results on the work record as displayed on th

electronic scale or in whole and tenth pounds to the nearest tenth pound. Record the

test weight on the certificate in whole and tenth pounds to the nearest tenth pound.

7. CERTIFICATION

Certify the analysis of millet on officially sampled lots on a commodity inspection 

certificate (FGIS-993). Issue a submitted sample certificate (FGIS-994) for samples 

submitted by an applicant or their agent
