Visual Reference Images Volume 1

Visual Reference Images (VRI) are used to ensure consistent and uniform application of grading lines and illustrate types of damage in conjunction with written descriptions. The visual grading aids system represents the foundation for the national inspection system's subjective quality control program, providing an effective management tool for aligning inspectors and assisting them in making proper and consistent subjective grading decisions. The system consists of a series of commodity specific VRI and descriptive text which help reduce the impact of normal perceptional differences between inspectors.



Volume One covers the grains standardized under the United States Grain Standards Act.
