View official standardAbout this standard
The United States Standards for Barley, maintained by the USDA Agricultural Marketing Service (7 CFR §§ 810.201-810.207), define grade factors including plumpness, test weight, damaged kernels, and foreign material for barley and malting barley classes. Vibe imaging workflows measure the same plumpness distribution and defect parameters these grades depend on.
