(b) Foreign material and fines. All matter other than whole flaxseed that passes through a 564 triangular-hole sieve, and all matter other than grains for which standards have been established under the Act, that remains in the sieved sample.

(c) Grades. U.S. Mixed Grain, or U.S. Sample grade Mixed Grain, and special grades.

(d) Heat-damaged kernels. Kernels and pieces of grain kernels for which standards have been established under the Act, that are materially discolored and damaged by heat.

Principles Governing the Application of Standards

§810.803   Basis of determination.

Each determination of damaged and heat-damaged kernels, and the percentage of each kind of grain in the mixture is made on the basis of the sample after removal of foreign material and fines. Other determinations not specifically provided for under the general provisions are made on the basis of the grain as a whole, except the determination of odor is made on either the basis of the grain as a whole or the grain when free from foreign material and fines.
