Preferred Label : sampling plan;
Detailed label : sampling plan in analytical chemistry;
IUPAC definition : A predetermined procedure for the selection, withdrawal, preservation, transportation
and preparation of the portions to be removed from a population as samples. Summarizing
the test values or observations from the selected portions yields an estimate for
the concentration of an analyte or a value for a property determined with a calculable
degree of uncertainty at a specified confidence level. A sampling plan includes the
designation of the number, location and size of the portions, and instructions for
the extent of compositing and for the reduction (in amount and fineness) of the portions
to a laboratory sample and to test portions. It may also contain acceptance criteria.
Some sampling plans do not include more than instructions for the statistical selection
of portions to be removed. Such plans should properly be designated as 'statistical
sampling plans'.;
