N.D. Admin Code 74-06-03-02 - Terminology and definitions

Terminology used in the "Official United States Standards for Grain", FGIS, USDA, Stock No. 001-016-00104-7 is used as appropriate in these mustard standards to facilitate communication; and equipment used by FGIS is used as possible.

1. "Broken seeds" refers to broken, but sound, mustard seeds of any size (or with any portion of seedcoat removed) not removed in the proper determination of dockage.

2. "Damaged seeds" includes seeds, except heat damaged seeds, that are shrunken or shriveled as result of frost damage, discolored from excessive weathering that has penetrated the seedcoat, heavily blotched, distinctly green or heated as interpreted from the crushing test, or otherwise distinctly damaged.

3. "Distinctly green seeds" refers to seeds having a vivid green color throughout the embryo as observed and recorded after the crushing test.

4. "Dockage" refers to all matter removed from the sample using the required standard method of dockage determination. Dockage is reported in percent and added to and made a part of the grade designation after subclass.

5. "Foreign material other than dockage" is all material other than mustard seed of the four subclasses after the removal of dockage (includes weed seeds, other grains, earth pellets or stones, sclerotia, "trash", etc.). This total foreign material is composed of:

a. A combination of seeds of cockle (Lychnis spp.), wild mustard (Brassica kaber), and rapeseed (Brassica campestris and B. napus);

b. Other weed seeds than those in subdivision a; and

c. All matter other than mustard or weed seeds of subdivisions a and b.

6. "Heat damaged seeds" refers to whole or broken mustard seeds which are discolored light tan to charcoal black by excessive respiration or any other heating or drying process and have a distinct burnt odor after crushing.

7. "Moisture percentage" refers to moisture percentage of the seed sample prior to dockage removal.

8. "N.D." in the grade designation refers to North Dakota.

9. "Odor" of mustard seed of any of the four subclasses should be the natural odor associated with sound seed, and applied favorably to the numerical grades 1 to 4. Any lot of mustard seed having a musty, sour, or otherwise objectionable odor will be graded North Dakota sample grade on account of "odor".

10. "Purity" refers to total percentage of the subclasses yellow, oriental, or brown, and to mixed mustard on basis of percentage of mustard seeds required to qualify for the mustard class.

11. "Sound seed" refers to whole or broken mustard seed not damaged by heat, sprout, frost, fungi, or otherwise damaged, or which do not appear distinctly green in the "crush" tests. The presence and percentage of distinctly green seeds and heat damaged seeds of mustard will be determined, by crushing with a roller, on a minimum of five strips of one hundred mustard seeds each. The determination will be made on clean seed after dockage removal.
