This is a growing component of our measurement services. The laboratory may have purchased a 3rd-party measurement standard because of its low price but then realizes that the certification is not science based. For example, the Certificate of Calibration lacks the transparency to substantiate the claim of metrological traceability, and the uncertainty intervals assigned to the “certified” reference values are not current and valid. To salvage the new reference standard, but before placing it into field service use, we certify the new standard with the appropriate scope of calibration using an advanced calibration model.
