Moisture testing – Chapter 2
Official Grain Grading Guide

Moisture specifications

The charts below outline the moisture specifications and conversion tables for each type of grain and lists the representative portion required to determine the moisture content of the sample.

Conversion tables are not available for all grains.

For wheat, oats and barley samples with low test weight, see Estimating moisture content for lightweight wheat, oats and barley samples.
For samples with moisture values above the range of the conversion table, see Estimating moisture content for high moisture samples.
For beans for which there are no conversion charts, see Estimating moisture content for beans with no conversion table.
For other grains, see Determining moisture content for special cases.

Tough and damp ranges for Canadian grains.
