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.
