Sec. 810.1402  Definition of other terms.

    (a) Broken kernels. All matter which passes through a 5/64 
triangular-hole sieve and over a 2-1/2/64 round-hole sieve according to 
procedures prescribed in FGIS instructions.
    (b) Broken kernels and foreign material. The combination of broken 
kernels and foreign material as defined in paragraph (a) and (f) of this 
section.
    (c) Classes. There are four classes of sorghum: Sorghum, Tannin 
sorghum, White sorghum, and Mixed sorghum.
    (1) Sorghum. Sorghum which is low in tannin content due to the 
absence of a pigmented testa (subcoat) and contains less than 98.0 
percent White sorghum and not more than 3.0 percent Tannin sorghum. The 
pericarp color of this class may appear white, yellow, pink, orange, 
red, or bronze.
    (2) Tannin sorghum. Sorghum which is high in tannin content due to 
the presence of a pigmented testa (subcoat) and contains not more than 
10.0 percent non-Tannin sorghum. The pericarp color of this class is 
usually brown but may also be white, yellow, pink, orange, red, or 
bronze.
    (3) White sorghum. Sorghum which is low in tannin content due to the 
absence of a pigmented testa (subcoat) and contains not more than 2.0 
percent sorghum of other classes. The pericarp color of this class is 
white or translucent and includes sorghum containing spots that, singly 
or in combination, cover 25.0 percent or less of the kernel.
    (4) Mixed sorghum. Sorghum which does not meet the requirements for 
any of the classes Sorghum, Tannin sorghum, or White sorghum.
    (d) Damaged kernels. Kernels, pieces of sorghum kernels and other 
grains that are badly ground damaged, badly weather damaged, diseased, 
frost-damaged, germ-damaged, heat-damaged, insect-bored, mold-damaged, 
sprout-damaged, or otherwise materially damaged.
    (e) Dockage. All matter other than sorghum that can be removed from 
the original sample by use of an approved device according to procedures 
prescribed in FGIS instructions. Also, underdeveloped, shriveled, and 
small pieces of sorghum kernels removed in properly separating the 
material other than sorghum.
    (f) Foreign material. All matter, except sorghum, which passes over 
the number 6 riddle and all matter other than sorghum that remains on 
top of the 5/64 triangular-hole sieve according to procedures prescribed 
in FGIS instructions.

    (g) Heat-damaged kernels. Kernels, pieces of sorghum kernels, and 
other grains that are materially discolored and damaged by heat.
    (h) Nongrain sorghum. Seeds of broomcorn, Johnson-grass, Sorghum 
almum Parodi, sorghum-sudangrass hybrids, sorgrass, sudangrass, and 
sweet sorghum (sorgo).
    (i) Pericarp. The pericarp is the outer layers of the sorghum grain 
and is fused to the seedcoat.
    (j) Sieves.
    (1) 1.98 mm (5/64 (0.0781) inches) triangular-hole sieve. A metal 
sieve 0.81 mm (0.032 inches) thick with equilateral triangular 
perforations the inscribed circles of which are 1.98 mm (0.0781 inches) 
in diameter.
    (2) 0.99 mm (2 1/2 /64 (0.0391) inches) round-hole sieve. A metal 
sieve 0.81 mm (0.032 inch) thick with round holes 0.99 mm (0.0391 
inches) in diameter.
