The amino acid subsample was mechanically divided from this composite. A part of the Official Grades, test weight was determined by drop-filling a dry quart measure from a height of 2 inches. Test weight in all grains provides an estimate of weight contained in a storage bin. For corn, test weight is considered a general indicator of quality because stress conditions of all kinds reduce test weight. Generally, lower test weight corn will not store well.
Dry kernels pack tighter in the cup.
A 250 gram whole grain sample is put in the WBT and the sample is broken. The corn that remains on top of the screen is weighed. All rights reserved.
