This article is an adaptation of my popular presentation, “Beyond the Sticker & the Cert (Ensuring Better Measurements & Reducing Risk).” Product manufacturers, testing labs, and calibration labs often overlook the importance of thoroughly reviewing calibration certificates, leading to potential measurement inaccuracies and increased risks.

In order for a measurement to be valid, i.e., to have measurement (metrological) traceability, it must be stated with its associated measurement uncertainty.
