Proposed approach for force transducers classification

Abstract

In accordance with the recent version of ISO 376:2011, the classification of the force transducers is based on the relative errors calculated from the calibration results. This classification approach doesn't take the uncertainty of measurement into consideration. It becomes one of the most important factors that must be utilized when making a classification decision based on of ISO/IEC 17025:2017. In this study a proposed approach for force proving instrument classification was developed. This approach is based on taking into account the calibration results uncertainty of the instruments as a decision rule for classifications. Since the expanded budget uncertainty is a combination of different parameters that may affect the classifications decisions so it is more realistic and more accurate for decision making. The results of this paper demonstrate a recommendation for ISO 376:2011 to modify its classification criteria for the force proving instruments in the upcoming version of this standard.

Metrology applied to Human Ecology: critical analysis of geospatial data for regionalization of Brazilian Anthromes

“…The SIGPC and the SIGC enable the use of this standard in the control of information, as they indicate differences between the expected and obtained results, through quality indicators (IBGE, 2011(IBGE, , 2013b. This enables correction and continuous improvement actions in the method (ISO, 2015a, 2015b, 2015c; Mahmoud et al, 2021), which is essential to adjust it to variations in different locations (IBGE, 2013b). In this way, the continuous control of the production of results helps in the characterization of the data (Koch et al, 2021;Mbaru et al, 2021;Peng et al, 2021).…”

“…In the method of land use and cover (IBGE, 2013a), the tool (ISO, 2017) refers to the re-evaluation of products that do not t the acceptance pro le (minimum precision) in the classi cation performed by the software (Liu et al, 2018;Mahmoud et al, 2021). At this point, one should also assume treatment of noise and trend (Magnusson, 2014;Thompson et al, 2002), presented in method validation, which points to the imprecision in the reading made by the computer program (Bayoudh et Intralaboratory comparisons this feature of the standard (ISO, 2017) depicts the comparison of data generated in different collection units by a responsible data-producing institution (IBGE, 2013b).…”

“…These posts are systemically associated with the central nucleus of the Brazilian Institute of Geography and Statistics (IBGE, 2013b), creating an unbroken chain of information (BIPM, 2017). The Central Nucleus compares the results of the collection points (IBGE, 2013b), which parallels this standardized tool (ISO, 2017; Mahmoud et al, 2021). Through this characterization it is possible to analyze the contribution of this tool to the structuring of the method.…”

“…Therefore, the use of reference values (ISO, 2015a) in the standard method of INDE (IBGE, 2013a) strongly helps in ensuring the quality of results (ISO, 2015b, 2015c, 2017) indexed on the platform. Furthermore, the results are composed of attributes such as uncertainty and error (VIM, 2012), which provides a better recognition of the areas (Bigdeli et al, 2018;van Wilgen, 2021) and allows for an understanding of how these two factors can distort the regionalization of anthromes (Mahmoud et al, 2021).…”

“…In this context, Metrology adds to Human Ecology by presenting tools that support the quality assurance of results (Brondizio et al, 2016;Steffen et al, 2015), either to assess reliability geospatial information through structures that attest to the operability of the methods and the results they generate (Mahmoud et al, 2021;Mittaz et al, 2019), or to propose schemes for data comparability and traceability through associated characteristics the measurement or estimation performed (BIPM, 2017; Fermam, 2012; Sené et al, 2017). In general terms, the ISO/IEC 17025(ISO, 2017) standard designates two metrological resources that contribute to this scope.…”
