### § 74-06-02-02. Procedure.

A representative portion of seven hundred fifty grams is properly divided from the uncleaned
sample and passed through the Carter dockage tester with settings as follows:
Slot 1. Oil sunflower riddle
Slot 2. No top sieve
Slot 3. # 8 sieve 6/64 triangle
Slot 4. # 6 sieve 5/64 triangle
Set Feed on # 6
Air Control on # 6

### § 74-06-02-03. Determination of dockage.

1. Determine dockage.
Dockage (Drop fraction or five-tenths percent).
Pan #1 Material over oil sunflower riddle. If any buckwheat is in this pan, remove and return to
dockage free buckwheat.
Pan #2 Material over # 8 sieve. This is the dockage free buckwheat.
Pan #3 Material through # 8 sieve. If over fifty percent of dockage, add to dockage. If over fifty
percent of cultivated buckwheat, return all of this material to dockage free buckwheat.
Pan #4 Material through # 6 bottom sieve.

Dockage consists of air dockage plus contents of pan #4. Dockage is defined as all matter
other than buckwheat which can be removed readily from a test portion of the original sample
by use of an approved device in accordance with the procedures prescribed in the Federal
Grain Inspection Manual. Dockage ranging from five-tenths percent to nine-tenths percent
shall be expressed as five-tenths percent, dockage ranging from one percent to one and
four-tenths percent shall be expressed as one percent, and dockage ranging from one and
five-tenths percent to one and nine-tenths percent shall be expressed as one and five-tenths
percent, etc.
2. Take test weight on dockage free portion (whole and half pounds only).
3. Check sixty gram dockage free portion for foreign material. Foreign material is defined as all
other matter other than buckwheat which remains in the sample after the removal of dockage
and shrunken and broken kernels.
4. Check sample for foreign odor.
5. Perform a moisture test (two hundred fifty grams sample as a whole).

### § 74-06-02-04. Type.

The type shall be designated by size, large or small, determined by sizing using an 8/64 x 3/4
slotted sieve, and shall be added to and become part of the grade name, e.g., No. 1 North Dakota
Large.
1. The designation is large when at least eighty percent of the buckwheat remains on top an
8/64 x 3/4 slotted sieve. The designation is small when over twenty percent of the buckwheat
passes through an 8/64 x 3/4 slotted sieve.
2. The determination of type shall be by a manual or mechanical method.
a. For the manual method, a representative portion of two hundred fifty grams of the
cleaned sample is sized using an 8/64 x 3/4 slotted hand sieve nested over a blank tray.
The sample is placed on the sieve and shaken lengthwise of the slots for twenty strokes,
a stroke being about twenty centimeters back and forth.
b. For the mechanical method, a representative portion of two hundred fifty grams of the
cleaned sample is sized over the Carter dockage tester as follows:
Air - off Top section - (8/64 x 3/4) slotted sieve
Feed - # 6 Center section - Blank tray
Riddle - nil
The machine is turned off only after the sample has passed over the sieve.
NOTE: All buckwheat passing through an 8/64 x 3/4 slotted sieve shall be weighed and
percentage determined.
History: Effective September 1, 1979.

### § 74-06-02-05. Standards for buckwheat.

For the purpose of the official grain standards of North Dakota for buckwheat:
Grade Minimum Test Weight Maximum Limits of Foreign Material
Large Small Percent
No. 1 North Dakota 45 48 1
No. 2 North Dakota 43 46 2
No. 3 North Dakota 40 42 4
Sample Grade - Buckwheat which has any commercially objectionable foreign odor, or is musty, sour, or is
heating, hot, or otherwise unfit for the higher grades; shall be graded Sample Grade Buckwheat with the
inspector's notation as to the quality and condition.
1. Dockage is all matter other than buckwheat which can be removed readily from a test portion
of the original sample by use of an approved device in accordance with the procedures
prescribed in the Federal Grain Inspection Manual. Dockage ranging from five-tenths percent
to nine-tenths percent shall be expressed as five-tenths percent, dockage ranging from
one percent to one and four-tenths percent shall be expressed as one percent, and dockage
ranging from one and five-tenths percent to one and nine-tenths percent shall be expressed
as one and five-tenths percent, etc.
2. Percentages, except in the case of moisture, shall be percentages ascertained by weight.
3. Percentage of moisture shall be that ascertained by the air oven or ascertained by any device
and method which give equivalent results in the determination of moisture. Moisture will be
shown on certificate (recommended safe storage level is sixteen percent or less).
4. Test weight per bushel [35.24 liters] shall be the weight per Winchester bushel or as
determined by any device and method which give equivalent results in the determination of
test weight per bushel [35.24 liters] when free from dockage.
5. Foreign material includes all other matter other than buckwheat, which remains in the sample
after removal of dockage, and shrunken and broken kernels.
6. All grades may contain three stones per five hundred grams; in excess of three stones per
five hundred grams up to two and five-tenths percent grade buckwheat, rejected "grade"
account stones; in excess of two and five-tenths percent grade buckwheat, sample salvage.

### § 74-06-02-07. Sample size.

The minimum sample size is seven hundred fifty grams for grading buckwheat. Samples of less
