Understanding an NIST Traceable Calibration

During an NIST- traceable calibration, the performance and accuracy of a measuring instrument or device is tested against an NIST-traceable standard. The standard is an instrument with a relationship to a standard reference material (SRM) provided by the National Institute of Standards and Technology. To prove this relationship, the standard has a certificate of compliance with traceability to NIST.

The traceability of a calibration lab’s standard, essentially its relationship to the SRM, is established through an unbroken trail of documentation that includes uncertainties. Following testing that’s performed against the standard, the calibration lab will issue an NIST-traceable calibration certificate to document the test results. This certificate verifies that the tested instrument is within – or has been adjusted to – its stated tolerance. The calibration certificate provided by a lab or a manufacturer has an expiration date, which is the date another calibration will be needed.

What Does NIST Do?

Established in 1901, the National Institute of Standards and Technology is a federal agency within the Department of Commerce. NIST is comprised of six laboratories working in the interest of measurement science, rigorous traceability and standards development.

NIST develops and maintains the national standards of measurement and documents the traceability of its reference standards. Its SRMs perform instrument calibrations, verify measurement accuracy and ensure U.S. measurement traceability.
