Sampling - Michigan Technological University
2009-1-14 Sampling procedures cover the practice of selecting representative quantities of test material in the field, to evaluate bulk materials. Examples of the test materials are bulk granular solids, slurries, sludges, grains, and solid fuels. It is necessary to be able to sample bulk materials during shipment and during processing operations.
