1 Purpose and scope

1.1 This standard establishes a method to estimate the percentage of commingled grain or seed from a previously harvested crop present in that of the next crop subsequently harvested by a combine harvester.

1.2 A standardized estimate of the level (percentage) of commingled grain present after cleaning all or parts of a combine harvester and/or flushing with a quantity of grain is produced from these procedures. Because of differences among various large- and small-seeded crop varieties as well as other harvest factors, estimates from this procedure should only be used as a comparative guide between machine treatments using these procedures and not as an absolute value of maximum commingled grain percentage for all crop conditions or any single sample value from one of the crops tested. This standard is without warranty of any kind, either expressed or implied. In no event shall the producers of this standard be liable for any damages including lost profits, lost savings or other indirect, incidental or consequential damages arising out of the use or inability to use this standard.
