has prepared this introductory document to promote the
sound evaluation of measurement uncertainty through
the use of the GUM and to provide a prelude to
the GUM Supplements and other documents JCGM is
producing [3, 4, 5, 6, 7, 8].
As in the GUM, this document is primarily concerned
with the expression of uncertainty in the measurement
of a well-defined physical quantity - the measurand -
that can be characterized by an essentially unique value.
The purpose of the GUM Supplements and the other
documents is to help with the interpretation of the
GUM and enhance its application. The GUM Supplements
and the other documents are together intended
to have a scope that is considerably broader than that
of the GUM.
This document introduces (a) measurement uncertainty,
(b) the GUM, and (c) the GUM Supplements and other
documents that support the GUM.
This introductory document is directed at (a) calibration,
testing and inspection laboratories in industry, and
laboratories such as those concerned with health and the
environment, (b) accreditation bodies, and (c) scientific
disciplines in general. It is hoped that it will also be
useful to designers, because a product specification that
takes better account of inspection requirements (and
the associated measurement) can result in less stringent
manufacturing requirements. It is also directed at academia,
with the hope that more university departments
will include modules on uncertainty evaluation in their
courses. As a result, a new generation of students would
be better armed to understand and provide uncertainty
statements associated with measured values, and hence
gain an improved appreciation of measurement.
This introductory document, the GUM, the GUM Supplements
and the other documents should be used
in conjunction with the "International Vocabulary of
Metrology-Basic and General Concepts and Associated
Terms" (VIM).
