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 workflows can measure some of the same visual characteristics — plumpness distribution, damaged kernels, and foreign material — for internal comparison and visual screening. Characteristics outside image-based measurement require the applicable official or laboratory method, and this does not constitute an official USDA grade.
