Development of a system to increase the legal metrological control of measuring instruments in Brazil

Abstract

Abstract. This article presents the development of a system used by the Brazilian Network of Legal Metrology and Quality -INMETRO and its delegated public bodies to increase the coverage of mandatory periodic verification on measuring instruments in Brazil, especially non automatic weighing instruments. Based on a governmental database of active establishments that allowed the choice of an specific economic activity, the system provides a list of establishments where measuring instruments are used to commercial transitions and, therefore, subject to periodic mandatory verification. As a result, the use of system increased the number of measuring instruments controlled in Brazil, revealed areas for improvement and provided references to set goals.

Metrologia, Ventiladores Mecânicos E a Covid-19

“…A Metrologia Aplicada às Ciências da Vida, ocupada das medições de parâmetros biológicos, é considerada um novo ramo do conhecimento (LUIZ et al, 2004). No Brasil as ciências metrológicas possuem ainda uma atuação fundamentalmente direcionada à regulamentação legal, em sua interação com o setor saúde (SORATTO et al, 2014).…”

Estimación de la incertidumbre en la calibración de esfigmomanómetros según OIML R16-1 desde una perspectiva de metrología legal

“…It is reported that the lack of metrological control or verification, as well as the inadequate frequency of verification of these instruments, are generally the cause of measurement errors, followed by an erroneous or inadequate diagnosis, which puts the well-being of the patient at risk. In another work [5], it is reported that INMETRO uses a system to perform periodic verifications of measuring instruments, pointing to a legal metrological control where the model approval processes as recommended by OIML R16-1, show the absence of the estimate. uncertainty for the case of sphygmomanometers.…”
