Test Weight of Corn

Zea mays L. subsp. mays (Maize Group)

Test weight of corn is a physical-technical indicator of bulk density that is not regulated by national quality standards but is used in logistics and international trade contracts.

In the reference 6 varieties crop Maize, where this is mentioned in the description.

In the domestic standardization system, the test weight of corn is not a quality grading indicator and is not regulated by the requirements of GOST 13634-90. Despite this, the parameter is in demand for export operations, where contractual requirements may be established, for example, in the range of 66–72 kg/hl, which aligns with international norms such as USDA standards.

Measurement of corn test weight is carried out using a chondrometer or NIR analyzers to determine bulk density. The indicator directly depends on the physical characteristics of the grain: moisture content, shape, plumpness, and impurity content. The primary practical significance of test weight for corn lies in calculating the loading volumes for elevators, sea vessels, and transport vehicles during storage and transportation.
