Description / Abstract:
Objective
The objective of this Standard is to ensure correctness and
acceptability of dimensional measurements.
Requirements
This Standard specifies requirements for preparation and
approval of dimensional measurement plans and for the use of
approved plans in making dimensional measurements.
Applicability
This Standard considers that a dimensional measurement method is
acceptable if its associated measurement uncertainty per the Guide
to the Expression of Uncertainty in Measurement (GUM) [2] meets
business needs, e.g., cost of measurements, consequences of pass
and fail errors, liability, specific policies, and customer
requirements. In assessing the acceptability of a stated measuring
procedure, management should take into account the importance and
difficulty of evaluating measurement uncertainty in such a way as
to quantitatively capture the effects of all significant sources of
measurement error.
Purpose
This Standard is intended for use by process and quality
engineers or personnel performing a similar function in planning
dimensional measurements.
