| 説明 | This is the 10,000 lb. test weight cart with some 10,000 lb. test weight standards loaded on the cart after the weights had been calibrated at the U.S. Department of Agriculture’s (USDA) Grain Inspection, Packers, and Stockyard Administration (GIPSA) Master Scale Depot in Chicago, IL on Jul. 2, 2013. USDA GIPSA entered into an agreement with the National Institute of Standards and Technology (NIST) and the Association of American Railroads (AAR) in 1980 transferring responsibility to USDA’s GIPSA to maintain the Master Scale facility in Chicago, IL and calibrate all the master scales in the continental U.S. annually.
