S. "Method".
The experimental, documented demonstration that
a general process (CMP) or a particular step (e.g.
sampling, data processing) has performed as expected and will continue to do so. Also, the experimental, documented demonstration that an
object (e.g. an apparatus or instrument) possesses
specified properties and will continue to do so
(Chap. 4, pp. 173, 174, 194, 195; Fig. 4.19).
A datum (accompanied by an uncertainty) derived
by chemometric treatment of the results obtained by
having many different laboratories process aliquots
of the same sample (a CRM) in order to determine
the same analyte. Related to referential quality
(Chap. 2, pp. 44,45,48, 51, 53, 54,69, 77, 91).
A separation technique occasionally used for gravimetric purposes that relies on the difference between the mass of the sample prior to and after controlled heating (in the presence or absence of a
reagent) (Chap. 6, p. 261).
