    1/ Compliance with the provisions of these standards does not excuse failure to comply with the provisions of the Federal Food, Drug, and Cosmetic Act, or other Federal laws.  

    Terms Defined  

    601 Definitions.  

    For the purposes of these standards the following terms shall have the meaning stated below.  

    (a) Class. There is one class: Lentils.

    (b) Damaged lentils. Whole and pieces of lentils which are distinctly damaged by frost, weather, disease, heat (other than to a material extent), immature, or other causes, except weevil or material heat damage or are distinctly soiled or stained by nightshade, dirt, or toxic material.

    (c) Defective lentils (total). The categories of defective lentils shall be weevil-damaged lentils, heat-damaged lentils, damaged lentils, and split lentils.

    (d) Dockage. Small underdeveloped lentils, pieces of lentils, and all matter other than lentils which can be readily removed by use of sieves and cleaning devices as set forth in the Pea and Lentil Handbook (see 606).

    (e) Dockage-free lentils. Lentils from which the dockage has been removed.

    (f) Fair color lentils. Lentils that are lightly to moderately discolored from storage or other causes to the extent they cannot be considered of good color

    (g) Foreign material in dockage-free lentils. All matter other than lentils, and including detached seedcoats.

    (h) Foreign material in thresher-run lentils. All matter other than lentils, and including detached seedcoats, which cannot be readily removed in the proper determination of dockage.

    (i) Good color lentils. Lentils that are practically free from discoloration and have the uniform natural color and appearance characteristic of the predominating lentil type.

    (j) Heat-damaged lentils. Whole and pieces of lentils which have been materially discolored as a result of heating.

    (k) Lentils. Threshed seeds of the lentil plant (Lens culinaris Moench), which after removal of the dockage, contain 50.0 percent or more of whole lentils and not more than 10.0 percent foreign material.

    (l) Skinned lentils. Lentils from which three-fourths or more of the seedcoat has been removed.

    (m) Split lentils. Pieces of lentils which are less than three-fourths of a lentil, and lentils in which the cotyledons are loosely held together.

    (n) Stones. Concreted earthy or mineral matter, and other substances of similar hardness that do not readily disintegrate in water.

    (o) Thresher-run lentils. Lentils from which the dockage has not been removed.

    (p) Weevil-damaged lentils. Whole and pieces of lentils which are distinctly damaged by weevils or other insects.

    (q) Whole lentils. Lentils with one-fourth or less of the cotyledons removed and with the remainder of the cotyledons firmly held together.

    (r) 9/64 round-hole sieve. A metal sieve 0.0319 inch thick, perforated with round holes 0.1406 (9/64) inch in diameter which are 0.1875 (3/16) inch from center to center. (The perforations of each row shall be staggered in relation to the adjacent rows.)

    (s) 12/64 round-hole sieve. A metal sieve 0.0319 inch thick, perforated with round holes 0.1875 (12/64) inch in diameter, which are 0.250 (1/4) inch from center to center. (The perforations of each row shall be staggered in relation to the adjacent rows.)

    (t) 15/64 round-hole sieve. A metal sieve 0.0319 inch thick, perforated with round holes 0.2343 (15/64) inch in diameter, which are 0.3125 (5/16) inch from center to center. (The perforations of each row shall be staggered in relation to the adjacent rows.)

    (u) Inconspicuous Admixture. Any seed which is difficult to distinguish from a lentil, including, but not limited to, vicia sativa.

    (v) Poor color lentils. Lentils that are severely discolored from storage or other causes to the extent they cannot be consider of fair color.

    (w) Immature lentils. Lentils that do not have a traditional lens-shaped profile due to immaturity. Immature lentils are characterized as having a thin or flat (wafer-like), wrinkled, and misshapen appearance. Lentils may also be discolored.

    (x) Contrasting Lentils. Lentils that differ substantially in size or color from the predomination lentil type.  

    Principles Governing Application of Standards  

    602 Basis of determinations.  

    (a) All factor determinations shall be made upon the basis of the lentils after the removal of dockage, with the following exceptions:

    (1) Dockage shall be determined upon the basis of the thresher-run lentils as sampled.

    (2) Color shall be determined after removal of dockage, defective peas, and foreign material.

    (b) Defects in lentils shall be scored in accordance with the order shown in 601(c); and once an individual lentil is scored in a defective category it shall not be scored for any other defect but it shall remain as a part of the sample for purposes of determining the percentages of other defects in the sample.

    603 Moisture.  

    Water content in whole peas as determined by an FGIS approved device in accordance with procedures prescribed in the Pea and Lentil Handbook and the Moisture Handbook (see 606).  

    604 Percentages.  

    All percentages shall be determined on the basis of weight and shall be rounded off in accordance with instructions shown in the Pea and Lentil Handbook (see 606). Percentages shall be stated in whole and tenth percent to the nearest tenth percent.  

    605 Interpretive line samples.  

    Interpretive line samples showing the official scoring line for factors that are determined by visual observation shall be maintained by the Federal Grain Inspection Service, U.S. Department of Agriculture, and shall be available for reference in all inspection offices that inspect and grade lentils.  

    606 References.  

    The following publications are referenced in these standards and copies will be made available upon request to the Federal Grain Inspection Service, U.S. Department of Agriculture.
