Metrology Evidence

Metrology & Traceability Assurance

TraceGauge can record the evidence used to establish metrological traceability; the database itself does not create traceability.

Records supported

  • As-Found and As-Left measurements
  • Multiple test points and acceptance limits
  • Reference/master standard IDs and status
  • Calibration laboratory and accreditation information
  • Measurement uncertainty and decision rules
  • Environmental conditions
  • Technician/reviewer approvals
  • OOT investigation and product-impact assessment

Traceability boundary

An unbroken traceability chain requires competent calibration activities, valid reference-standard certificates, uncertainty appropriate to the intended measurement, and traceability to SI or another accepted reference. TraceGauge is a recordkeeping/control system for that evidence.

External certificates

Qualification should verify that records link the actual certificate/evidence for standards used, including certificate number, laboratory, dates, uncertainty and scope where required.

Certificate meaning

A TraceGauge-generated PDF is a controlled software output. It is not, solely by being generated, proof that a measurement is ISO/IEC 17025 accredited or SI-traceable.
