NIST, the National Institute of Standards and Technology, plays a crucial role in metrology – the science of measurement. Their work focuses on advancing measurement science to enhance economic security and improve quality of life. NIST provides various resources and activities related to metrology, including calibrations, standard reference materials, test methods, and tools for evaluating measurement uncertainty. A key aspect of NIST’s metrology work is ensuring metrological traceability, which involves establishing an unbroken chain of calibrations to specified reference measurement standards, typically national or international standards based on the International System of Units (SI). NIST assures the traceability of measurement results it provides, either directly or through official programs or collaborations. Other organizations are responsible for establishing the traceability of their own results to national reference standards maintained by NIST or to other specified reference standards.
