Towards traceability of CT dimensional measurements

© Springer International Publishing AG 2018. There can be no discussion on the accuracy of a measurement result without its proven traceability. Traceability is a fundamental property of a measurement that ensures the measured quantity is comparable to the international definition of the unit with which it is expressed. The task of achieving traceability requires a thorough understanding of the measurement procedure and, in particular, the operating principle of the measuring instrument. In this chapter, the concept of traceability is introduced as it applies to dimensional measurements. The role of instrument calibration in establishing traceability of its measurements is presented for earlier coordinate measuring systems, to serve as a precursor to the discussion on how CT instruments can be calibrated. Finally, methods for assessing task-specific measurement uncertainty are discussed.
