THE DISSEMINATION OF THE FORCE UNIT IN ITALY: CALIBRATION OF MATERIAL TESTING MACHINE INTERCOMPARISON
Abstract
One of the most important activities at European (EA) and National level of the National Accreditation Body (NAB) is the organisation of a series of interlaboratory comparisons (ILC), to verify the measurements capability of the calibration laboratories.
In 2001 one ILC, for the calibration of uniaxial testing machines, was organised in Italy by SITIMGC with the IMGC-CNR as reference laboratory. In the present paper the main results obtained during the ILC are discussed, in particular a regression analysis was applied to evaluate the differences on the repeatability and accuracy given by the different laboratories.
