NIST stands for the National Institute of Standards and Technology, they’re a non-regulatory government body under the Department of Commerce that sets national measurement standards within the United States.
Depending upon a company’s quality procedures a NIST Traceable Certificate of Calibration may be needed to be done periodically for test and laboratory equipment.
At other times a higher level of testing, such as an ISO 17025 test and calibration might be required, depending upon how critical the market or application that is being served. It is up to the end user to determine what level of calibration services are needed for a given application, many companies have quality procedures in place that dictate what type of testing is required for specific equipment.
