- Abstract:
- In accordance with ISO 17025, measuring and test equipment, including gear and spline artefacts must have been traced back to recognized national or international primary standards through an unbroken traceability chain. This is the reason why there have been national gear standards and gear standard measuring equipment in Germany since the sixties, for example for the elements: profile, helix, pitch, radial run-out of gearings and roughness. In contrast to this, no direct link-up to spline artefacts has so far been made at the PTB for splines. If one proceeded in compliance with the DKD traceability criteria applicable to other geometrical measurands within the DKD, a large number of PTB calibrations against the PTB's reference standards or comparison measurements of spline gauges with the PTB would have to be performed, of course at relatively high cost. In this lecture, the most recent traceability strategies for different levels will be discussed.
By bringing up this topic, the author aims to point out that one should start thinking about the necessity of defining traceability criteria within the meaning of ISO 17025, which are uniform all over the world so that mutual recognition of the measurement results for gears and splines can be achieved on the international level. - Keywords:
