Also known as: uncertainty of measurement, expanded uncertainty, GUM.
Why it matters in NDT
A remaining wall of 6.1 mm against a 6.0 mm minimum is a pass only if the uncertainty of the reading is understood. Inspection companies accredited to ISO/IEC 17025 or reporting measurements under ISO/IEC 17020 need a defensible statement of uncertainty for quantitative results.
In AMPS
Uncertainty statements and decision rules belong in your procedures and report templates; AMPS reproduces them exactly because reports are generated from your own Word templates, and the calibration certificates that feed the uncertainty budget are filed on the equipment page.
