1. PURPOSE

This directive establishes procedures under the Agricultural Marketing Act of 1946, as

amended, for the factor analysis of crambe seed

2. REPLACEMENT HIGHLIGHTS

This is a new directive

3. GENERAL INFORMATION

There are no classes, subclasses, or grades for crambe seed. Inspection is on a factor

only basis. The factors analyzed are foreign material and test weight per Winchester

bushel

DEFINITION OF CRAMBE SEED

Crambe seed (Crambe abyssinicia Hochst) consist of 50.0 percent or more of whol

crambe seed before the removal of foreign material

Whole kernels are kernels with more then 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 crambe. However, if analysis is necessary, make it before

removing foreign material on a representative portion of approximately 25 grams

4. FOREIGN MATERIAL

Foreign material is all material other than crambe seed that you can remove from the

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

Federal Grain Inspection Service (FGIS) instructions

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

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

mechanically cleaned crambe seed and approximately 30 grams of crambe seed cut 

from the mechanically cleaned sample

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

and handpicked foreign material
FGIS Directive 9180.73 April 5, 2002

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

 Carter Dockage Tester:

a. Set air control on 

b. Set feed control to 2 

c. Insert No. 2 riddle in the riddle carria

d. Insert No. 8 triangle hole sieve in the middle sieve carriage.

e. Insert No. 2 round hole sieve in the bottom sieve carria

f. Run sample portion through the Carter Dockage Teste

g. Monitor the crambe seed removed by the aspirator, making sure the

hulls in the air collection pan are empty. If the hulls are not empty and

contain mature seeds, adjust the air setting down

Mechanically separated foreign material is: aspirated material in air collection pan;

materials over No. 2 riddle (excluding crambe seed); material that passed through th

No. 2 sieve (bottom collection pan

Combine crambe seed that passed over the No. 8 sieve and over the No. 2 sieve to 

form the mechanically cleaned sample

STEP 2. Procedure for determining handpicked foreign material

 a. Cut approximately 30 grams from the mechanically cleaned sampl

 b. Handpick the 30-gram mechanically cleaned sample and remove all

 material other than crambe seed

Calculating Foreign Material

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

 x 100 = Percent of mechanically separated foreign material

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

 base factor

STEP 3. (Weight of handpicked foreign material ÷ Weight of handpicked portion) x 10

 = Percent of handpicked foreign material

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

 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 th

certificate to the nearest tenth percent.

6. TEST WEIGHT

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

using an approved device according to procedures prescribed in FGIS instructions

Basis of Determination. Determine test weight after the removal of mechanicall

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 described 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 analysis of crambe seed on a commodity inspection certificate (FGIS-993). A lot

inspection certificate is issued for those lots that are officially sampled. A submitted 

sample certificate (FGIS-994) is issued for a sample submitted by an applicant or their 

agent
