Definition of Traceability

Traceability: the ability to show that a standard or an instrument has been calibrated or certified by a traceable standard which is then calibrated or certified by another traceable standard and so on, thus the standard or instrument is eventually related back to the established national standards.

Establishment or Traceability

Larson Davis uses independent test laboratories to calibrate, verify, repair and/or certify its reference standards. The laboratories are audited at regular intervals to verify traceability to the standards maintained by the U.S. National Institute of Standards & Technology or to other accepted physical constants. Larson Davis instruments are traceable through an unbroken chain of comparisons to standards maintained by or traceable to the United States National Institute of Standards and Technology (NIST).
