WAC 16-213-210
Procedures. (1) The determination of
dockage shall be on approximately nine hundred seventy-five to
one thousand twenty-five grams cut from the representative
sample.
(a) The Carter dockage tester shall be set up as follows:
(i) Set the air control at number six;
(ii) Set the feed control at number six;
(iii) Use the number two riddle in the riddle carriage;
(iv) Use no sieve in the top sieve carriage;
(v) Use the number eight sieve in the middle sieve
carriage;
(vi) Use the number six sieve in the bottom sieve
carriage.
(b) Buckwheat produced in the Pacific Northwest tends to
be exceptionally large and dockage cannot be accurately
determined using the standard method. For this large
northwest buckwheat, the Carter dockage tester shall be set up
as follows:
(i) Set the air control at number three;
(ii) Set the feed control at number four;
(iii) Use the number twenty-five riddle in the riddle
carriage;
(iv) Use no sieve in the top sieve carriage;
(v) Use the number eight sieve in the middle sieve
carriage;
(vi) Use the number six sieve in the bottom sieve
carriage.
(c) Dockage will then consist of:
(i) The material removed from the air collecting pan;
(ii) Material over the number two or twenty-five riddle. If any buckwheat is in this pan, remove and return to dockage
free buckwheat;
(iii) Material through the number eight sieve. If by
weight, it is fifty percent or more of material other than
buckwheat, return all of it to the dockage. If by weight, it
is more than fifty percent buckwheat, return all of it to the
dockage free buckwheat;
(iv) Material through the number six bottom sieve.
(d) Record the percentage of dockage on the pan ticket. When applicable, the percentage of dockage shall be shown on
the inspection certificate. The percentage of dockage when
equal to 0.5 percent or more shall be stated in terms of half
percent, whole percent, or whole and half percent, whichever
is applicable, with other fractions disregarded as shown in
the following examples:
0.50 to 0.99 percent is expressed as 0.5 percent;
1.00 to 1.49 percent is expressed as 1.0 percent;
1.50 to 1.99 percent is expressed as 1.5 percent, etc.
(2) The determination of foreign material shall be made
on a representative portion of approximately sixty grams cut
from the work sample after the removal of dockage. The
percentage of foreign material shall be shown on the pan
ticket and the inspection certificate to the nearest tenth of
a percent.
(3) The determination for moisture shall be made on a
representative portion of exactly two hundred fifty grams
obtained from the representative sample before the removal of
dockage. The percentage of moisture shall be shown on the pan
ticket and the inspection certificate in whole and tenths of a
percent to the nearest tenth percent.
(4) The determination for distinctly low quality and
Washington sample grade factors shall be made on the basis of
the lot as a whole and/or a representative portion of
approximately one thousand grams cut from the representative
sample before the removal of dockage. Distinctly low quality
factors shall include:
(a) Animal filth. Buckwheat containing two or more
rodent pellets, bird droppings, or an equivalent quantity of
other animal filth shall be graded Washington sample grade.
(b) Broken glass. Buckwheat containing two or more
pieces of broken glass shall be graded Washington sample
grade.
(c) Castor beans. These multicolored bean-like seeds of
the castor-oil plant have been found to be highly toxic to
animal life. Buckwheat containing three or more castor beans
shall be graded Washington sample grade.
(d) Crotalaria. The seeds of crotalaria (CROTALARIA spp.)
are highly toxic to animal life. These seeds can be various
colors and are generally "kidney" or "boxing glove" shaped. Buckwheat containing three or more crotalaria seeds shall be
graded Washington sample grade.
(e) Unknown foreign substance. Buckwheat containing four
or more pieces of an unknown foreign substance shall be graded
Washington sample grade. Pelletized material other than feed
pellets shall be considered an unknown foreign substance. Feed pellets in buckwheat are considered dockage or foreign
material, depending on where they are found during grading.
When buckwheat is found to be Washington sample grade on
one or more of these factors, this fact and the reasons
therefore shall be shown on the pan ticket and the inspection
certificate even though the buckwheat may be Washington sample
grade on another factor.
(5) The determination of stones shall be made on a
representative portion of approximately one thousand grams of
buckwheat after the removal of dockage.
(6) The determination for test weight per bushel shall be
made on a representative portion of buckwheat ranging in size
from one and one-eighth to one and one-quarter quarts after
the removal of dockage. The test weight per bushel of
buckwheat, whether or not this factor determines the grade,
shall be shown on the pan ticket and the inspection
certificate in whole and half pounds. A fraction of a half
pound shall be disregarded.
(7) The determination of type shall be made on a
representative portion of approximately two hundred fifty
grams cut from the work sample after the removal of dockage. One of the following methods may be used:
(a) The mechanical sieving method.
(i) Mount an 8/64 x 3/4 slotted sieve and the bottom pan
on the mechanical sieve shaker with the sieve perforations
parallel to the direction of the movement. The sample is
placed on the sieve and shaken lengthwise of the slots for
twenty strokes.
(ii) All the material passing through the sieve shall be
weighed and the percentage determined to the nearest tenth of
a percent. This percentage shall be shown on the pan ticket
and the inspection certificate.
(b) Hand sieving method.
(i) Mount an 8/64 x 3/4 slotted sieve on a bottom pan.
(ii) Place the two hundred fifty gram portion in the
center of the pan.
(iii) Hold the sieve level in both hands with elbows
close to the body and the sieve perforations parallel to the
direction of the movement.
(iv) In a steady motion move the sieve left to right
approximately ten inches and then return from right to left.
(v) Repeat the operation twenty times.
(vi) All the material passing through the sieve shall be
weighed and the percentage determined to the nearest tenth of
a percent. This percentage shall be shown on the pan ticket
and the inspection certificate.
(8) The determination for the special grade "weevily"
shall be made on the basis of the lot as a whole and/or the
representative sample before the removal of dockage. Buckwheat is considered infested and shall be graded weevily
when:
(a) The work sample contains one live weevil and any
other live insect injurious to stored grain.
(b) The work sample contains one live weevil and the
balance of the representative sample contains one live weevil
or any other live insect injurious to stored grain.
(c) The work sample, or the work sample and the balance
of the representative sample combined, contains no live
weevils but does contain five or more other live insects
injurious to stored grain.
(d) Two or more live weevils are found in, on or about
the lot. When buckwheat is found to be weevily, this fact
shall be shown on the pan ticket and on the inspection
certificate in accordance with grade designation procedures.
(9) To provide uniform certification the following
procedure shall be observed when writing grade designations on
pan tickets and inspection certificates:
(a) The word "Washington" preceded by the abbreviation
"no." and the numerical grade, or preceded by the words
"sample grade," as the case may be, shall be shown first;
(b) The word "large" or "small" shall be shown next;
(c) The word "buckwheat" shall be shown next;
(d) When applicable, the special grade "weevily" shall be
shown next;
(e) When applicable, the word "dockage" together with the
percentage thereof.

otherwise distinctly low quality shall be graded Washington
sample grade buckwheat with the inspector's notation as to
quality and condition.
