The present work presents a prospective analysis of the implementation of Norm ISO17025 and PNQ criteria in the Laboratory of Calibration of the CRCN. The adopted methodology was described by Griffth. The results showed an average increasing of the 70.25 in all evaluated parameters, demonstrating the importance of the implementation of the quality norms and accreditation.

The acoustic pressure field mapping system of Ultrasound Laboratory (Labus) of Institute of Metrology, Standardization, and Industrial Quality (Inmetro) is being implemented, based on Standard IEC-61102. This system will be capable to estimate ultrasound pressure field parameters from biomedical transducers, essential step to calibration and certification of ultrasound equipments. The data acquisition is carried out on a water bath, where a positioning system moves a hydrophe, which produces electrical signals in response to waterborne acoustic signals, over the transducer acoustic field. This work presents the implementation of acoustic pressure field mapping system, based on IEC-61102 that defines the necessary steps to acoustic beam assessment and calibration.

In Brazil, beta radiation metrology was based on a 30-years-old irradiation system. Aiming to fulfill a regional metrological gap and safety requirements, a new secondary standard for beta radiation – the BSS2- was installed at the CDTN/CNEN. Results of three metrological characteristics of the BSS2 are presented.

Objectifying to present the legal metrology Brazilian model, this article will concept its aspects, showing the characteristics, procedures and the main lines. In this context, the National Institute of Metrology, Standardization and Industrial Quality (Inmetro - Instituto Nacional de Metrology, Standardization e Qualidade Industrial – Instituto Nacional de Metrologia, Normalização e qualidade Industrial), considering its mission, the effective and efficient warranty of the activities in the whole country (Brazil has continental dimensions), the structure aimed for the legal metrology work is responsibility of the Legal Metrology Direction (Dimel – Diretoria de Metrologia Legal), with the support of the Metrological State Organizations (OME – Órgãos Metrológicos Estaduais) for that Inmetro has delegated the operational activities of metrological verifications and supervision of measurement instruments in use and pre-packed goods. This OME constitute the Brazilian Net of Legal Metrology and Quality – Inmetro (RBMLQ-I – Rede Brasileira de Metrologia Legal e Qualidade-Inmetro). Dimel does, directly, the Metrological Technical Regulation (RTM – Regulamento Técnico Metrológico) and the type approval of measurement instruments, being responsible for the management of the RBMLQ-I work.
The operation of the RBMLQ-I in accordance with Inmetro strategies and politics for legal metrology activities, including the normative prescriptions, the way of action, the appropiation act and the resources are primordial factors for the best attainment of the Institute’s mission, in the metrological guarantee of the measurements to the citizen protection and the consolidation of a free trade and a fair invitation to bid.

Advances in metrology underpin innovation, enable improvements in quality of life, and unlock potential from other areas of science. Increased demand for top-level metrology in traditional areas, allied with the need to support emerging areas of technology, requires a new approach from the European NMIs. Increasing levels of cooperation in R&D will enable the NMIs to significantly improve impact from funding that can not reasonably expected to keep pace with demand growth. Within the iMERA project a coordinated European Metrology Research Programme will be prepared and the institutional and legal conditions for its implementation will be generated.
