NIST calibration, and NIST calibration alone, can ensure the traceability of an instrument’s indications. Only NIST calibration can calibrate or repair an instrument with services that trace back to the National Institute of Standards and Technology. Wikipedia gives the formal definition of “traceability” as “the ability to chronologically interrelate uniquely identifiable entities in a way that is verifiable.” But what does that actually mean?

NIST calibration is dependent on six critical elements to be deemed as actual NIST calibration:

NIST calibration requires that all of these steps be taken. When looking for a reputable calibration lab, make sure that they comply with these criteria for NIST traceability and NIST calibration.

What else should a calibration lab be able to offer?
