Description / Abstract:
Objective
This technical report provides guidance in assessing the reliability
of a statement of measurement
uncertainty in question, that is, in judging whether that stated
uncertainty can be trusted to
include the values that could reasonably be attributed to the measured
quantity (measurand) with
which that stated uncertainty is associated.
Applicability
This report is most applicable to statements of uncertainty in the
results of dimensional
measurements based upon the ISO Guide to Expression of Uncertainty in
Measurement (GUM). (Also
called ANSI/NCSL Z540-2.)
Purpose
This technical report helps parties to avoid potential, or resolve
actual, disagreements over the
magnitude of a stated measurement uncertainty, particularly when that
uncertainty is part of a
determination of conformity of a manufactured product to a dimensional
specification.
