Wheat Hardness


This Reference Material (RM) was prepared and analyzed by the Federal Grain Inspection Service (FGIS) program, Grain Inspection Packers and Stockyards Administration of the U.S. Department of Agriculture. It is intended primarily for use in calibrating instruments used for determination of hardness of bulk or single kernel wheat.


RM Description 8441a* Wheat Hardness


Wheat Numbers


Hard-1 through Hard-5; 5 


Soft-1 through Soft-5; 5 


* Developed by the U.S. Department of Agriculture Trace Elements in Botanicals


These SRMs and RMs are for use in evaluating the reliability of analytical methods for the determination of major, minor, and trace elements in botanical materials, agriculture food products, and materials of similar matrix. The materials can be used for quality assurance when assigning values to in-house control materials.

These RMs are intended for use in evaluating analytical methods for the determination of summative composition of lignocellulosic materials (hardwood, softwood, herbaceous biomass, and agriculture residues). The RMs can also be used for quality assurance when assigning values to in-house control materials.
