São dois, portanto, os objetivos: conceituar os processos de informação jurídica e conceituar os processos de sua validação jurídica. Buscou-se, pois, recompor ponto a ponto o itinerário do surgimento à validação jurídica das tecnologias de validação da informação desde as marcas pessoais pré-históricas até a tecnologia criptográfica assimétrica que proporcionou o advento da assinatura digital. Os conceitos de forma, de norma e de padrão são analisados com o fulcro na problematização do tema da validação nos processos humanos de comunicação da informação. / Abstract- This paper means to explore legal validation of information processes, wether the information is legal or legalized by its validation process. It had, thus, two main objectives, i.e.: to conceptualize legal information processes and to conceptualize legal validation processes pursuant to the latter. A step-by-step trace of the path from the advent to the legal validation of information processes – since the beginning of it as pre-historical personal marks, up to the latest asymmetric cryptographic technologies that allow the upcoming of digital signatures. The concepts of norm, form, pattern and standard are thus analyzed, meaning to further comprehend the ever-evolving quest for validation in human information communication processes.

Efici?ncia energ?tica. Portaria n? 144/2015. INMETRO. Fator de pot?ncia. Fluxo luminoso. Efici?ncia energ?tica. The objective of this study was to evaluate the energy efficiency of LED light bulbs (Light Emitting Diode) commercialized in the Brazilian market in the period of 2015/2016 and the development of a low cost test system to measure the mains voltage, current, consumption and power factor of LED lamp. For the evaluation of the LED lamps, the equipment available in the laboratories of the Eldorado Research Institute was used, and as a reference, the requirements established by Ordinance No. 144/2015 of the Instituto Nacional de Metrologia, Qualidade e Tecnologia - INMETRO, published on March 13, 2015. This Ordinance made it mandatory for manufacturers and importers to certify LED bulbs as of February 26, 2016. In order to carry out this work, a set of LED lamps from different manufacturers was acquired in the retail market to be subjected to functional tests of consumption of energy (watts), power factor (PF), luminous flux (lumens) and luminous efficiency (lumens/watt). The data obtained were compared with the nominal values declared by the manufacturers, as specified in the INMETRO ordinance. The results show that 11% of the samples failed in the energy consumption test and 83% failed in the power factor test. The developed test system was validated comparing its measurements with the results obtained in the tests carried out in INMETRO certified laboratory. Through this work it was possible to have an overview of the energy efficiency of LED bulbs currently commercialized in the country. / O presente trabalho teve como objetivo avaliar a efici?ncia energ?tica de l?mpadas com tecnologia LED (Light Emitting Diode) comercializadas no mercado brasileiro no per?odo de 2015/2016 e o desenvolvimento de um sistema de teste de baixo custo para medir a tens?o da rede el?trica, a corrente, o consumo e o fator de pot?ncia de l?mpada LED. Para a avalia??o das l?mpadas LED foram utilizados os equipamentos dispon?veis nos laborat?rios do Instituto de Pesquisas Eldorado e como refer?ncia os requisitos estabelecidos pela Portaria n? 144/2015 do Instituto Nacional de Metrologia, Qualidade e Tecnologia - INMETRO, publicada em 13 de mar?o de 2015. Esta Portaria tornou obrigat?ria para fabricantes e importadores a certifica??o das l?mpadas LED a partir de 26 de fevereiro de 2016. Para a realiza??o deste trabalho foi adquirido no mercado de varejo um conjunto de l?mpadas LED de diferentes fabricantes para serem submetidos a testes funcionais de consumo de energia (watts), fator de pot?ncia (FP), fluxo luminoso (lumens) e efici?ncia luminosa (lumens/watt). Os dados obtidos foram comparados com os valores nominais declarados pelos fabricantes conforme especificado na portaria do INMETRO. Os resultados demonstram que 11% das amostras falharam no teste de consumo de energia e 83% falharam no teste de fator de pot?ncia. O sistema de teste desenvolvido foi validado comparando suas medi??es com os resultados obtidos nos testes realizados em laborat?rio certificado pelo INMETRO. Atrav?s deste trabalho foi poss?vel ter um panorama amostral da efici?ncia energ?tica das l?mpadas LED comercializadas atualmente no pa?s.
