Traceability Assessments for Weights and Measures


This 2 hour webinar will introduce Metrological Traceability for Weights and Measures officials and directors. Metrological traceability is a characteristic of a measurement result. A laboratory is not traceable. A standard is not traceable. A NIST Test Number is not traceable. This session covers the definition of metrological traceability and the essential elements that must be documented to provide objective evidence that a measurement result is in fact, traceable. It will also cover methods associated with assessing a measurement system or process for evidence of metrological traceability.

  • IDENTIFY and DESCRIBE the definitions of Metrological Traceability;
  • IDENTIFY the essential elements required to demonstrate metrological traceability;
