Laboratorio Tecnológico del Uruguay (LATU) is the National Metrology Institute of Uruguay and has the obligation to maintain the national standards stated by National Law 15298. At present LATU is acting as a secondary laboratory as well as a primary laboratory. LATU was ISO 17025:2005 DKD (Deutscher Kalibrierdienst) accredited from 2001 up to 2007. By that time LATU decided to support its Capabilities of Measurement and Calibration (CMCs) at CIPM-MRA (Mutual Recognition Arrangement between national metrology institutes (NMIs)) by peer assessment. A Peer Review has been done in 2008 in order to get the QSTF (Sistema Interamericano de Metrología, Quality System Task Force) approval. “New “CMCs for Industrial Thermometers have been approved by the JCRB on September 2010. CMCs claimed for Standard Resistance Platinum Thermometers ( SPRTs) calibration at fixed points have not been approved yet because there were some requirements of traceability of employed cells that were not fulfilled but will be solved properly. The declared CMCs have been chosen by LATU in order to cover the increasing calibration services required by the industry and the secondary calibration laboratories. To demonstrate its technical competence an support its declared “CMCs” LATU has also participated at bilateral and regional comparisons. In recent years LATU, the National Accreditation Body (OUA), the Standards Institute, the National Institute of Quality and Compliance Bodies have become Members of a new Institution to strengthen the Quality Infrastructure of the country (SUNAMEC). As part of this new activities, LATU is giving training courses to the secondary laboratories performing calibrations in temperature that want to get accredited by the National Accreditation Body and to act as Technical Evaluators or Auditors when required by OUA. It is expected, that in the future and in the frame of new accredited and recognized temperature calibration laboratories, LATU could strengthen its activities in maintaining its own national standards, developing new calibration services and performing comparisons as pilot laboratory for Uruguay and also regionally. The role of secondary laboratory could be diminished and therefore the activities as a reference laboratory in investigation would be benefited. This paper describes all the activities carried out at LATU in Temperature in the last years to reach the goals stated and the coming ones that have to be done to help developing main objectives as a country in this field.
