Annex I
those to be routinely analysed by a laboratory (Chap.
8, pp. 309, 323, 327, 329, 341).
Bulk sample or primary sample. The result of the
first selection from the object. Usually of a large size.
Composite sample. The result of combining several
portions of a bulk sample.
Convenience sample. One selected in terms of accessibility, cost-effectiveness, efficiency, etc.
Grey sample. A sample the composition of which is
known only approximately (Chap. 5, pp. 202, 221,
222,240).
Laboratory sample. A portion of the object that is
submitted, in an appropriate container, for analysis
by the laboratory.
Random sample. One selected in such a way that any
portion of the object will have a specified probability
(e.g. 95%) of being withdrawn.
Representative sample. A portion of the object that
is selected by applying a sampling plan consistent
with the analytical problem addressed.
Selective sample. A sample collected by following a
selective sampling procedure.
Stratified sample. One withdrawn from a stratum or
well-defined zone of the object.
Test sample (aliquot). The portion of a laboratory
sample that is eventually subjected to the analytical
process.
White sample. A sample with well-defined properties which, with some exceptions, remain virtually
constant as a whole (Chap. 5, pp. 202, 240).
S. "Sampling".
The action or series of actions that ensures an unequivocal relationship between the sample aliquot
subjected to a CMP and the result it produces
(sample traceability) (Chap. 3, pp. 133, 138).
S. "Standard".
A measure of expeditiousness of CMPs. The number
of samples that can be processed per unit time (e.g.
hour, day) (Chap. 2, p. 82).
A generic term used to refer to the substeps of the
preliminary operations of the CMP performed in
order to condition the test sample or aliquot for
measurement of the analytical signal (second step of
the CMP) (Chap. 4, pp.146, 150, 161, 168).
An operation by which one or more portions (aliquots) of an object are chosen for individual or joint
