The present master s degree dissertation entitled Metrology in standards, standards in metrology was motivated by explicit recommendations included in the National Metrology Plan (PNM) - which became an instrument of the Brazilian metrology policy, by force of a Interministerial Decision from CONMETRO, that had proposed specific actions to strenghten the Brazilian system of standardization, prioritizing the implementation of a technical committe for standardization in metrology within the ABNT structure. As complementary functions of industrial technology, metrology and standardization are treated not only as essential inputs necessary for the development of industrial competitiveness and quality of life enhancement, but also as intrinsic elements in equating vulnerabilities which restrict access of Brazilian products to competitive markets because of technical barriers to international trade. Thus, within the context of recommendations made by PNM, this master s degree research considered: (i) a study of the modus operandi of international standardization organizations, so as to perceive the way through which metrology inputs are added to international standards; (ii) an analysis of practices by national standardization organizations in industrialized countries so as to capture their experience in developing metrology standards; (iii) interviews with active experts in metrology and standardization with the purpose of defining a performance pattern in order to equate technical standards of industry in Brazil; (iv) a description of the most outstanding facts which had an impact on leveraging technical standardization in the country, providing subsidies to equate existingobstacles; (v) an analysis of the shortages and vulnerabilities of the Brazilian standardization system, thus consolidating knowledge and a critical vision in order to plan this master s dissertation which consisted of conceiving and formulating the conceptual fundamentals of a technical committee for standardization in metrology, to be implemented in ABNT s organic structure, as a strategy to enhance the Brazilian standardization system, and (vi) standardization demand research in metrology. With the aim of distinguishing the demand for standardization in metrology from the demand for metrology in standardization, this research was developed along three different lines: (a) at Brazilian standardization committees (ABNT/CB) and industry standardization organizations (ONS) which make up the organic structure of the Brazilian Association for Technical Standards (ABNT), so as to know the specific needs for metrology in standardization activities, as well as, the difficulties related to the use and application of metrology fundamentals as inputs to the technical standardization process; (b) with metrology and standardization experts in order to subsidize the development of the interface of a new cooperation rationale, and (c) research in forum specialized in metrology so as to identify standardization demands, pointed out throughout respective dissemination hierarchical chains of base units and derived from the International System of Units (SI). In addition tothe data bank which was consolidated by study and research developed and which led to a broad reflection on the existing correlation between metrology in standards and standards in metrology, the following results, which also came out of this master s degree dissertation, can be highlighted: (i) development of a new concentration area in technical standardization, created for the Post Graduate Program in Metrology at the Catholic University (PUC-Rio) in Rio de Janeiro; (ii) introduction of a process to build knowledge and development of human resources in standardization; (iii) the recent creation of ABNT/CB-53, the Brazilian Committee for Standardization in Metrology, whose genesis, conception, framework and implementation came out of the current master s degree work in metrology and which, officially , supplies Brazilian society with a technical forum for standardization in metrology. This decision has already been approved and ratified by the Technical and Deliberative Bodies of the Brazilian Association for Technical Standards (ABNT). Thus, this Master dissertation not only has identified concrete demands on metrology standardization but also shall contribute, through the technical committee conceived, to the enhancement of the Brazilian standardization system in metrology, since technical standard is considered an strategic input to the industrial and socioeconomic development.
