A
representative sample is needed to ensure the inspection results reflect the quality and condition of the lot being inspected. A representative sample is a sample that is obtained by official personnel, maintained under the control of official personnel, and is obtained following procedures established in the directives and handbooks issued by the Federal Grain Inspection Service.
Sampling procedures are defined for stationary lots using probe samples; or samples obtained from the grain stream during the loading or unloading process by diverter-type, mechanical, automatic Ellis cup, and pelican samplers.
There are sampling procedures for both bulk and packaged lots.
