Abstract

Laboratorio Tecnológico del Uruguay, LATU, is the National Metrology Institute of Uruguay, signatory of the CIPM Mutual Recognition Arrangement (CIPM MRA), has Calibration and Measurement Capabilities (CMCs) in temperature that were fi rst published in the BIPM Key Comparison Data Base (BIPM, 2009) in June 2004. LATU was a DKD Laboratory accredited in Mass, Balances and Temperature from 2001 until June 2007 when it was decided to adopt the CIPM criteria for proving compliance with ISO/IEC 17025 through a Peer Review process. The LATU on site Peer Review was carried out in January 2008, as part of the process. During the evaluation, a bilateral intercomparison was performed between PTB and LATU at the ITS- 90 fi xed points covering the range from Hg TP to Zn FP with PTB acting as the Pilot Laboratory. In this paper the results are presented and discussed in order to support the declaration of better Calibration and Measurement Capabilities (CMCs) and substitute the declared ones.
