Verifying Measurement Uncertainties for Every Test Point Against Your Lab’s ISO/IEC 17025 Scope of Accreditation
Digitalization of business processes is essential for future metrology, and all stakeholders, such as calibration labs, customers, and Accreditation Bodies (ABs), will need to move into the 21st century. A critical use-case for digitization is the process of verifying measurement uncertainties on an accredited certificate of calibration.
To accomplish this, we need digital representations of a Scope of Accreditation (SoA) containing a calibration lab’s calibration measurement capabilities (CMC). But digitization is more than just a lab’s PDF copy of their SOA found on the Accreditation Body’s (AB) website.
Using the NCSLI 141 MII Committee’s beta version of a “Metrology Taxonomy” database used for creating a digital version of a Scope of Accreditation, it is now possible for a computer to verify every test point’s measurement uncertainty against the Lab’s SoA. This paper will demonstrate the steps required (with sample code) to modify a Digital Calibration Certificate (DCC) by adding taxonomy tags, using those tags to compare the uncertainties in the DCC against the measurement uncertainties in the lab’s SoA, and then show the user what, if any, measurement uncertainties are not in accordance with the lab’s SoA.
