Description / Abstract:
This part of ISO 15530 specifies the evaluation of measurement
uncertainty for results of measurements obtained by a CMM
(coordinate measuring machine) and by using calibrated workpieces
or measurement standards. It provides an experimental technique for
simplifying the uncertainty evaluation of CMM measurements, whose
approach (substitution measurements) leads to measurements being
carried out in the same way as actual measurements, but with
calibrated workpieces of similar dimension and geometry instead of
the unknown workpieces to be measured.
Non-substitution measurements on CMMs are also covered, as are
the requirements of the uncertainty evaluation procedure, the
measurement equipment needed, and the reverification and interim
check of the measurement uncertainty.
NOTE The evaluation of measurement uncertainty is always related
to a specific measuring task.
