A quantity of material transferred on one occasion and covered by a single set of
shipping documents. It may consist of one or more lots or portions of lots. The presence
of different lots in a consignment is important from the point of view of the sampling
plan and the interpretation of the results of analysis. The term 'population
' is used as the general term for the quantity of parent material being sampled when
it is immaterial if the parent body is a consignment, lot, batch, entity, etc.
