§51.2713 Application of tolerances. 

The tolerances provided in these standards are on a lot basis and shall be applied to a composite

sample representative of the lot. However, any container or group of containers in which the

peanuts are obviously of a quality materially different from that in the majority of containers shall

be considered a separate lot, and shall be sampled separately. 

Definitions 

§51.2714 Similar varietal characteristics. 

"Similar varietal characteristics" means that the peanut kernels in the lot are not of distinctly

different varieties. For example, Spanish type shall not be mixed with Runners. 

§51.2715 Whole. 

"Whole" means that the peanut kernel is not split or broken. 

§51.2716 Split. 

"Split" means the separated half of a peanut kernel.

skins. 

§51.2719 Unshelled. 

"Unshelled" means a peanut kernel with part or all of the hull (shell) attached.

following: 

(a) Skin discoloration which is dark brown, dark gray, dark blue or black and covers more than

one-fourth of the surface; 

(b) Flesh discoloration which is darker than a light yellow color or consists of more than a slight
3

yellow pitting of the flesh; 

(c) Sprout extending more than one-eighth of an inch from the tip of the kernel; and,
