The New version of the German torque calibration standard DIN 51309:2005-12 a comparative overview

摘要

In December 2005, the new version of the DIN 51309 was issued by DIN, the German Institute for Standardization. This standard takes into account some fundamental ideas about the target application of a torque transducer, for example high-level inter-comparison measurements or measurements in industrial environments. Two cases are considered and two different calibration results are calculated on the basis of a standard calibration procedure. For some inter-comparisons, the hysteresis of the transducer does not have any influence on the result and is therefore excluded. This paper shows, on the one hand, the new version in comparison with other standards (e. g. EA-10/14) and some guidelines of the DKD, the German Calibration Service, and describes, on the other hand, its application to torque reference machines.
