A GERMAN TORQUE COMPARISON FROM 20 N · m TO 200 N · m AND ITS RESULTS

Dirk Röske

Abstract

In October 2009, the members of the German DKD Torque Committee (FA 10) agreed to carry out a comparison of torque calibrations according to the German torque calibration standard DIN 51309:2005-12 in the range from 20 N · m to 200 N · m using very stable torque transducers as travelling standards. The pilot laboratory was the torque working group at PTB. Thirteen accredited laboratories from Germany, together with another German laboratory without accreditation and an Austrian laboratory, participated in this comparison. All measurements were carried out in 2010 and 2011, and the first results were discussed in 2012. The report on the comparison was expected to be published later in 2013. <BR />This paper summarizes the results for discussion in the international community. In general, there was very good agreement between the results of the participants and the pilot laboratory.
