ASME B89.7.2

Abstract

<strong>Objective</strong> <br>The objective of this Standard is to ensure correctness and acceptability of dimensional measurements. <br><strong>Requirements</strong> <br>This Standard specifies requirements for preparation and approval of dimensional measurement plans and for the use of approved plans in making dimensional measurements. <br><strong>Applicability</strong> <br>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. <br><strong>Purpose</strong> <br>This Standard is intended for use by process and quality engineers or personnel performing a similar function in planning dimensional measurements.
