Establishing HVI Calibration Standards

James L. Knowlton


The main objective of the Cotton Program's production of High Volume Instrument (HVI) calibration standards is to meet the annual demand while maintaining year to year establishment consistency. Each year, over 40,000 pounds of HVI calibration cotton and over 200 sets of HVI color and trash tile calibration standards are produced. Consistency in value establishment of all HVI calibration standards is achieved by maintaining links to reliable reference standards. Through careful planning and execution of detailed procedures, the Cotton Program's Standardization and Quality Assurance Branch supplies practically all HVI users throughout the world with accurate HVI calibration standards.
