Metrology

Scope:

• This section is NOT intended to provide comprehensive and exhaustive information on the field of metrology. However, the links noted below should provide information across the entire field of metrology.

• This section is intended to provide an overview of metrology, with a focus on Measurement Uncertainty Budgets and their relationship to Measurement System Analysis (specifically Gauge R&R), calibration, and other metrology principles.

This section will also provide useful references to standards, and - where appropriate - links to actual standards and other references.

Useful references and standards include:

• GUM (Guide to the Expression of Uncertainty in Measurement)

• VIM (International Vocabulary of Metrology)

Related concepts include:

• Measurement System Analysis.

• Measurement Uncertainty Budget

• Calibration Management

Good references may be found at:

• NIST - Measurement Process Characterization

• NIST -Uncertainty Analysis (Highly recommended!)

• NIST - The NIST Reference on Constants, Units, and Uncertainty (Uncertainty of Measurement Results)

• NIST - Engineering Metrology Toolbox

• BIPM

• HN Metrology

  • Dr. Nielsen's uncertainty course online: Estimating Measurement Uncertainty (Discounted - Half Off)
