Description / Abstract:
This part of ISO 22514 defines a procedure to validate measuring
systems and a measurement process in order to state whether a given
measurement process can satisfy the requirements for a specific
measurement task with a recommendation of acceptance criteria. The
acceptance criteria are defined as a capability figure
(CMS) or a capability ratio
(QMS).
NOTE 1 This part of ISO 22514 follows the approach taken in
ISO/IEC Guide 98-3, Guide to the expression of the uncertainty
in measurement (GUM), and establishes a basic, simplified
procedure for stating and combining uncertainty components used to
estimate a capability index for an actual measurement process.
NOTE 2 This part of ISO 22514 is primarily developed to be used
for simple one-dimensional measurement processes, where it is known
that the method uncertainty and the specification uncertainty are
small compared to the implementation uncertainty. It can also be
used in similar cases, where measurements are used to estimate
process capability or process performance. It is not suitable for
complex geometrical measurement processes, such as surface texture,
form, orientation and position measurements that rely on several
measurement points or simultaneous measurements in several
directions.
