27.31—Classification of Cotton.
For the purposes of sub section 15b (f) of the Act, classification of cotton is the determination of the quality of a sample in accordance with the Official Cotton Standards of the United States for the color grade and the leaf grade of American upland cotton, the length of staple, and fiber property measurements such as micronaire. High Volume Instruments will determine all fiber property measurements except leaf grade and extraneous matter. High Volume Instrument colormeter measurements will be used for determining the official color grade. Cotton classers, designated as such by the Director, will determine the official leaf grade and extraneous matter, and authorized Cotton Program employees will determine all fiber property measurements using High Volume Instruments.
