The SIT activity to disseminate physical quantities in Italy: calibration of material testing machine intercomparisons

Carlo Ferrero, Luciano Bianchi

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 accredited Laboratories. In 1999, 2001, 2002, 2004 four ILCs, for the calibration of material testing machines, was organised in Italy by SIT. 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.
