Moisture testing – Chapter 2
Official Grain Grading Guide

Introduction to moisture testing

Moisture testing means analyzing a grain sample for the percentage of moisture contained within it.

Moisture content can affect the test weight and the appearance of the grain. Grain that is too moist is susceptible to deterioration.

Moisture tests are performed on samples free of dockage.

Industry Services will determine the moisture content of grain using either NIT, a Model 1200A moisture meter or Model 919/3.5 moisture meter. Specific Work Instructions for moisture testing are available to Canadian Grain Commission staff at K:\Isqms\Work Instructions-Instructions de travail\National-Nationale\English.

Samples testing within 0.5% (+) or (-) of the tough, damp, moist or wet cut off levels, are to be retested three (3) times using different moisture meters when possible. The final reported moisture content will be an average of the three tests.
