DISSEMINATION OF THE TORQUE UNIT IN ITALY: INTERCOMPARISON RESULTS ON TORQUE WRENCHES

C. Ferrero

Abstract

One of the most important activities of the National Accreditation Body (NAB) in the framework of the European cooperation for Accreditation (EA), is the organisation of a series of Interlaboratory Comparisons (ILC), to verify the measurements capability of the accredited calibration laboratories. In 2002 one ILC, for the calibration of torque wrenches, was organised in Italy by SIT (Sistema Italiano di Taratura) with the IMGC-CNR as pilot laboratory. In the present paper the main results obtained during the ILC are discussed, in particular the differences on the repeatability and accuracy given by the different laboratories are compared and evaluated.
