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.

MetE-215 Materials Processing Laboratory EXPERIMENT

2017-11-12  SAMPLING: Sampling is the art of securing a small weight of sample as a representative fraction of relatively large lot. To be representative, a sample must contain an adequate number of particles, and the sample must have been selected in a fair way. There are many ways of taking samples either manually or by a machine.

1976-12-1  Miner. Process., 3: 289--312. This paper is a summary of the general theory of sampling published (in French) by the author in 1975 (to be published in English by Elsevier, probably in 1977). Sampling is a random process and its theory is a study of the numerous errors liable to take place in the course of its realization.
