ASME B89.7.3.2:2007(R2021)

Annotation of standard text ASME B89.7.3.2:2007(R2021) :

The primary purpose of this Technical Report is to provide introductory guidelines for assessing dimensional measurement uncertainty in a manner that is less complex than presented in the Guide to the Expression of Uncertainty in Measurement (GUM).  These guidelines are fully consistent with the GUM methodology and philosophy. The technical simplifications include not assigning degrees of freedom to uncertainty sources, assuming uncorrelated uncertainty sources, and avoiding partial differentiation by always working with input quantities having units of the measured.  A detailed discussion is presented on measurement uncertainty concepts that should prove valuable to both the novice and experienced metrologist. Worked examples with an emphasis on thermal issues, are provided. Intended for design, drafting, mechanical, manufacturing, production, tool/gage, quality, process and project engineers, CAD/CAM/CAE specialists, inspectors and educators across a broad range of global manufacturing. Special emphasis on aerospace, automotive, medical device, precision instrumentation and related industries.
